Image Segmentation Based on Multiple Means Using Class Division Method Abstract— Image segmentation is the process of partitioning a digital image into multiple segments. Image segmentation is typically used to locate objects and boundaries (points, lines, curves, etc.) in images. Segmentation is an important part of many automated image recognition systems. The goal of segmentation is to simplify and/or change the representation of an image into units that are easier to analyze. It is the process of assigning a label to every pixel in an image such that pixels with the same label share certain visual characteristics. A histogram based image segmentation method is presented which divides the whole image into sub regions based on two …show more content…
Some of the features are intensity of the pixels, boundary of the objects in the images and color. Segmentation is a preprocessing method for isolating objects, which can be used further for processing. The level to which subdivision is to be carried out depends on the problem being solved. Two approaches to segmentation are edge based [1] – [3] and region based [4] – [6] techniques. Edge based techniques make use of the property of discontinuity whereas region based methods exploit the property of similarity. Numerous algorithms using these approaches have been proposed for image segmentation. Another classification for segmentation techniques are based on contextual or non-contextual information. Non-contextual methods take no account of spatial relationships between features in an image and group pixels together on the basis of some global attribute, e.g. grey level or colour. Contextual techniques additionally exploit these …show more content…
Using the discriminant criterion, an optimal threshold was selected, so as to maximize the separability of the resultant classes in gray levels. The procedure used only the zeroth and the first-order cumulative moments of the gray-level histogram. The method can be extended to multithreshold problems. Experimental results showing good values were presented to support the validity of the method. In [9], an interval type 2 (IT2) fuzzy entropy based approach is used to compute optimum thresholds for multistage gray scale image segmentation. By finding the maximum IT2 fuzzy entropy of the gray scale image, the optimum thresholds are computed. A termination criterion for multistage segmentation is also proposed based on the range of computed entropy values of the images. Several experimental results are shown to demonstrate the performance of our proposed algorithm which outperforms type 1 (T1) fuzzy based methods. In [10], a method for relaxation of the ultrafuzziness measurement by considering ultrafuzziness for background and object fuzzy sets separately, was proposed. The method optimizes ultrafuzziness to decrease uncertainty in fuzzy system used type II fuzzy sets. Experimental results on several images showed the effectiveness of the method. SOLUTION
Edge detection is widely used for detecting discontinuities in an image. Feature 7 is calculated in following way. The input face image is first converted
The knowledge base consists of a collection of fuzzy if-then rules of the following form: $R^{l}$: if $x_1$ is $F_1^{l}$ and $x_2$ is $F_2^{l}$ and $ldots$ and $x_n$ is $F_n^{l}$, then is $G^{l},~l=1,2, cdots ,n$, where $x=[x_1,cdots,x_i]^{T}$ and $y$ are the FLS input and output, respectively. Fuzzy sets $F_i^{l}$ and $G^{l}$, associated with the fuzzy functions $mu_{{F_i}^{l}}(x_i)$ and $mu_{{G}^{l}}(y)$, respectively. $N$ is the rules inference number. \Through singleton function, center average defuzzification and product inference cite{shaocheng2000fuzzy}, the FLS can be expressed as: For any continuous function $f(x)$ defined on a compact set $Omegain R^n$, there exists a fuzzy system $y(x) = heta ^T

After, the color space transformation we are going to extracts the texture vector from that image using sparse texture model. The texture vectors are represented as a set of distributions which is used to cluster the texture data using K-means clustering algorithm. Finding the number of clusters which consists set of texture distributions used to calculate TD metric. After, calculating the TD metric, the image is over segmented using SRM algorithm, which results the image being divided into large number of regions. Next, each region is independently classified as representing normal skin or lesion based on the textural contents of that region.
Terence Davies film, “The Long Day Closes” portrays the life of a young homosexual boy living in a postwar society. The main protagonist Bud, represents Davies experience of the good and troubled times that childhood and his sexuality brought him. The Tammy’s in Love scene flawlessly applies mise-en-scene, cinematography, editing and sound to depict the underlying message of finding yourself, a theme that is emphasized throughout the film. The use of mise-en-scene signifies the importance of the setting and surroundings by allowing the viewer to make connections between imagery and plot relevance.
Lauren Tarshis and Kristen Lewis the authors of "Is Anything Wrong With This Picture?" use lots of text structure to strengthen their writings. One unique text feature they often use is called a text box. Inside it lists facts about proper etiquette. For example, "Do not serve yourself food unless invited to by adults" (Tarshis & Lewis 25). This fact from a text box gives an example of a rule from somewhere else in the world (Netherlands 1530).
There will be two images being discussed in this essay. The first image was called “9/11/2001” by Art Spiegelman and Francoise Mouly. The second image was “What So Proudly We Hailed” by Carter Goodrich. The reason these images were chosen was because they have many differences, but they also have a lot in common. This essay will contain the color, date, prices, color, and what are the similarities and differences between these two images.
In today 's society the most commonly know thing many Americans enjoy doing is going out to eat, going to the movies and working out. There are so many different types of way a person can exercise, usually people prefer going to the gym and work out. Many people also enjoy outdoor sport like running, playing sports, group exercise, weight lifting as their form of exercise. Most of the people who attend a gym, go to lift weight, in fact some of those people commit to losing weight instead of lift weight for muscle. Those that enjoy lifting weights often enjoy working out in the privacy of their home, at community centers like YMCA, at a health club or a gym.
A photograph can mean so much to different people, but it’s ultimate purpose is to capture an important moment in someone’s life and be able to hold onto a physical copy of a memory. Photographs enact a certain nostalgia for the past, the good times or perhaps an important person or location; it’s a memory you want to last indefinitely. It’s a subject many people don’t touch on when they examine a film like Blade Runner (1982), but director Ridley Scott’s film does place an emphasis on the importance of photographs and what they can mean to people. The film depicts photos as a gateway to nostalgia, the immortalization of important figures and how photographs can deceive their owners. When you hold onto a photography they are generally a preserved version of a past memory that is important or a time of happiness.
Imagery is a powerful tool that great authors use to draw the reader into the story and make them feel as if they are living alongside the characters that have been so diligently created. Ray Bradbury was no stranger to this technique. Some would argue his use of imagery throughout his work is genius. He had the ability to paint such a vivid a picture for the reader, that one feels as if they are seeing the events of the story unfold before their eyes. His use of imagery went beyond simply describing something or someone looks like; Bradbury was able to touch all of the reader's senses.
The movie Hidden Figures by Theodore Melfi is talking about the civil rights and equality of men and women in 1970 's to 1990’s. The Mise-en-scene means "setting up a scene. " There are six elements that make up mise-en-scene acting, costume and make-up, setting, lighting, composition or space and lastly. In Hidden Figures, the mise-en-scene helps audiences to become closer to the story and have the same feeling as those main characters. The director uses many different kind of shout angles to show the unbalanced between black people and white people at that time and the color and lighting also help the director can present the emotions that the characters are facing different kind of events or people.
The Ontology of the Photographic Image André Bazin André Bazin through “The Ontology of the Photographic Image” examines how the mechanically produced photographic image is superior to the manual plastic arts for preserving humans and reality through representation. Bazin explores the existence of the photographic image through his essay. Plastic arts were used in the Egyptian civilization to preserve human beings.
Artificial selection, sometimes called selective breeding, is the process of finding desired traits or characteristics in two separate individuals of the same species and breeding those individuals to hopefully produce an offspring with all the desired traits or characteristics combined. This process is done in a controlled environment by humans. Artificial selection has become huge in horse breeding. Owners can take a horse known for its speed and agility and mate with a horse with a good temperament and hopefully the offspring will be a combination of both horses. I have a big aquarium in my living room and other than a Plecostomus that aids in keeping the tank clean, the only fish I have are called Glofish.
Crime Scene Processing Emily King 0551488 FRSC 3010H October 23rd 2015 Properly processing a crime scene is extremely important and can determine the outcome of a case. If evidence is collected incorrectly it may get destroyed or contaminated. When there are only trace amounts of evidence, it is very important that all of it is collected properly. The most important part of crime scene investigation is the investigators. In order to assess the crime scene, each investigator must be competent and know how to do their job correctly.
