Moving object segmentation is the important task in video surveillance and conferencing systems. Background subtraction methods for a relatively static background are widely exploited for moving object segmentation and detection in image sequences. However there are several issues like noises, shadows, dynamic background and illumination problem. This paper presents a new approach that combines wavelet approach with the Independent Component Analysis (ICA) for segmenting the moving objects. Our study shows improvements on the above mentioned problems and highly tolerable to changes in indoor and outdoor lighting conditions. The experimental results show the superiority of proposed algorithm over popular methods. Introduction: Reliable detection …show more content…
Moving object segmentation refers to the techniques that extract and locate the objects of interest in an image. There are some techniques that can be used to extract moving objects such as: optical flow, temporal differencing, and background subtraction. In between them background subtraction method is the common approach for identifying the moving objects in image sequences because of their flexibility and effectiveness. Background subtraction depends on subtracting the current image with the background image. Although when we are applying background subtraction method, we need to deal with some critical situations such as: illumination problem, noisy image, sudden change of light, small movements of non static objects etc. In signal processing independent component analysis (ICA) is a method for separating multivariate signal into additive subcomponents. There are some assumption related to the ICA approach, these are: all source signals are statistically independent and in order to …show more content…

Each position is around 10 or 20 m from each other. A total of 16277 images has been extracted, and two in- dependent subsets of images have been created, i.e., one for training the system composed of 5514 images (1047 positive samples of 509different panels and 4467 negative samples) and the other for testing the system composed of 10763
xi (x)$ and any positive constant $delta$, such that: where there exists an ideal parameter vector $ heta ^*$ to estimate the value of the vector $ heta$. The optimal parameter vector $ heta ^*$ can be defined as: According to Lemma 1, in order to estimate the
Multilinear principal component analysis (MPCA) is a mathematical procedure that uses multiple orthogonal transformations to convert a set of multidimensional objects into another set of multidimensional objects of lower dimensions. There is one orthogonal (linear) transformation for each dimension (mode); hence multilinear. This transformation aims to capture as high a variance as possible, accounting for as much of the variability in the data as possible, subject to the constraint of mode-wise orthogonality. MPCA is a multilinear extension of principal component analysis (PCA).
et us assume that $A_{ij}$ is the power received (expressed in dBm)by the frequency band $F_{i}$ at the time $T_{j}$. We have represented the data collected during our spectrum measurement by using a N $ imes$ M matrix designed by L. The matrix L is defined as: %%%%%%%%%%%%%%%%%%%%%%%%%% [ L = [A(F_i,T_j)]= egin{bmatrix}

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.
I am a team captain for a youth organized Relay For Life team through the American Cancer Society. As a team captain I experience I large amount of stress and pressure to provide the best opportunities for my team members to raise money, enjoy themselves, and fight against cancer. This summer I team member who has been a part of the team for at least five years, shared with me her opinion of the 2015 event. The day after the 24 hour event, late at night, I received an exceptionally long text message. As I was exhausted from being awake for over 28 hours I was asleep and did not see the message until I woke up in the middle of the night.
Tim Burton uses camera movements, camera angles, and sound in Big Fish, Edward Scissorhands, and Charlie and the Chocolate Factory to create the right mood for the audience to feel. Creating the right mood allows the audience to connect to the movie and to be intrigued by the movie. In Edward Scissorhands, Burton uses camera movements to create a sad mood. In a flashback, the camera moves with the inventor, who made Edward, as he takes Edward's hands out of a box and walks over to Edward before he dies, without getting to put Edward's real hands on.
RELATED WORK Milton Wider, Yin M. Myint et al [8], discusses the comparative results of three thresholding segmentation methods. From this comparison it can be clearly seen that the proposed method is the most appropriate method for appendix image segmentation. When analyzed the extracted appendix image, it can be concluded that the normal probe view is the best transducer position. The Appendix ultrasound images with five different probe positions are taken using Aplio MX, Toshiba ultrasound machine available in the lab. J. Lam, C. Pahl, et al [9], proposed a series of image processing method including image enhancement, image segmentation and edge detection before measuring the appendiceal.
Lastly, the lab results were evaluated using the Support Vector Machine for classification and the small-scale in-the-wild
TITLE PAGE INTRODUCTION It is stated that most people strongly believe they have very accurate visual experience. Accordig to them, seeing as a visual perception is considered as the most trustworthy perception which is used to comprehend what is happening in the environment. However, research has shown that visual perception is not very trustworthy as people think (Rensink, n.d). In other words, people overestimate their visual perception accuracy.

Surveillance cameras are a staple for ensuring the security of any building regardless of whether it is a home or a commercial establishment. They are available in different models, and when a homeowner intends to a security camera for his home, an outdoor device can be the ideal choice, particularly when he is planning a trip along with his family members for a week or so. As nobody will be available in the home during this period, an outdoor security camera can be installed to record the happening in the place, when there is nobody around. If you 're someone who fears for the safety of your family and you want to make sure that you do everything you can to deter criminals from breaking into your home, then the best way to do that is to install a CCTV surveillance system as soon as possible.
Technology will evolve, as it is in its natural way to do so. Thus, in the car manufacturing area the purpose for the near future is to produce autonomous cars. People love the idea of making driving more enjoyable and comfortable, and less stressing by continuously keeping the steering wheel and pushing the pedals. Having such technology available is great, but everyone is thinking about comfort, enjoyment and pleasure of traveling by car. There are more sensitive matters that must be discussed regarding autonomous cars, and some of them are responsibility and ethics.
