Chapter 1 Introduction INTRODUCTION 1.1 Overview In recent times, the world of photography has attained mammoth growth as every individual has the craving to capture various moments of his or her lives with a photograph. With the advent and rise of smart phones, high-resolution images, “selfies” etc are just a click away. But, to capture a particular moment with that perfect photograph in which everyone looks their best is indeed an herculean task for the photographer as well people in the photograph, for all to pose correctly at the same instant. Also people tend to browse through several shots clicked, in order to identify that one particular image which is best of the lot. Seldom does a photograph capture what we perceive with …show more content…
Its goal is to overcome the limitations of traditional photography using computational techniques to enhance the way we capture, manipulate, and interact with visual media. Face detection is the first step, which refers to localizing human face in a photograph. Face detection is a computer technology that determines the locations and sizes of human faces in digital images. Facial feature points are generally referred to as facial salient points such as the corners of the eyes, corners of the eyebrows, corners and outer mid points of the lips, corners of the nostrils, tip of the nose, and the tip of the chin. Detection of facial feature points is often an important step in computer vision applications such as face identification, facial expression recognition, face tracking and lip reading. Blink detection is the mechanism of finding if the eyes in the face detected are open or closed. Smile detection is a process of finding whether the user is smiling or not and if smiling to find out the extent to which the user is

Figure 9.4 – Stream When the stream starts, OpenCV, which is running on the server, starts detecting and recognizing faces and displaying the results in a list that resides on the right sidebar. A green box appears, containing the information and the image of the recognized face. If the detected face is unrecognized, a red box appears, containing the face of the unknown individual. Figure 9.5 – Detecting & Recognizing Faces Right after an unrecognized face is caught, an email is sent as an alert for the security guards, containing the unrecognized face of the individual, alongside the date, the time and the IP Camera’s information.
There's an old saying that says; “A picture is worth a million words.” Photography is an important
Street and commercial photography are two very different styles with different intentions yet they sometimes have a few things in common. These two styles can be portrayed in so many different ways. I will be comparing and contrasting the work of Zun Lee, a street photographer who specialises in portraiture and Matthew Coughlin, a commercial photographer who also specialises in portraiture. Portraiture may be a standout platform amongst the most established types of visual representation. A portrait is a picture about an individual; it may be a painting, photograph or an other alternative representation.
Nearly every time our family eats in Cracker Barrel, we get a laugh about some of the old photographs hanging on the wall. It is hard to believe that those people had to be perfectly still for a very long time to just take one picture. In the time it has taken me to write this paragraph, my dad took a bunch of pictures of our cat. On just our phones alone, the picture quality, speed, and color were probably unimaginable 100 years ago.
Everyday we encounter new and familiar faces. We are able to distinguish our mother’s face from a stranger’s face due to the facial recognition processes that we have stored in our brains. Facial recognition is one of the many processes of object-recognition. Many of us are not aware of the brain’s role in facial recognition because it is a process that we are not consciously doing. Face recognition differs from object recognition in a few ways.
People have always been judged since the beginning of time. From the pitch of their voice all the way to the way they walk. It is sometimes a first instinct for many people and appearances can also be the determining factor for many positions. Although, the most common way people are judged is by their appearance, which is completely inhumane since nobody is perfect. So it obviously isn’t fair to judge by physical appearances alone.
Let’s go back in time. Let’s think how we get all these amazing pictures that hold so many memories to us. As they say a picture is worth a thousand words. Who invented photography? What did they do to get it started?
By the power of photography, the natural image of a world that we neither know nor can know, nature at last does more than imitate art: she imitates the
Just as Sontag emphasises in her essay, photography is useful tool that captures the memories, defenses against anxiety, and brings familiarity. In additional, personally I also believe that photos can empower the world by sharing
Photographs are works of art that capture moments in time. They’re important because they document instances, which can later complete or create history. Looking at a photograph one is immediately intrigued. After studying the composition of the photo its meaning comes to mind, one begins to wonder why such a photo was taken. The overall meaning will have different effects depending on the viewer, but one must wonder again.
INTRODUCTION Now a day’s a facial recognition system is a computer application and it is used for automatically identifying or verifying a person . This is done by comparing selected facial features from the image and a facial database. Face Recognition System focuses on contactless man and machine interface. The human face plays an important role in our interaction and people’s identity.
CHAPTER TWO LITERATURE REVIEW AND THEORETICAL FRAMEWORK 2.1 Introduction: This chapter would analysis photography under conceptual review as the main concept of this study, it would look at the history of photography, types of photography, and types of cameras available till date, followed by empirical review and lastly the theoretical framework would come at the end of this chapter. 2.2.1 History of photography The concept of photography was coined out of a Greek words “photo” meaning light and “graphy” meaning writing and when merged together the word means writing with light. Although different scholars proffered different definitions of photography, the concept, however still remains the same.
In this essay I will write about the strengths and weaknesses of perception as a way of knowing. Perception is the way we perceive the world through our senses. We use all five of our senses, which are sight, hearing, smell, taste and touch to understand the world and interpret it. We can then say it’s a Primary way of knowledge. We can also say that, because the senses is the way our body communicates, we have at least three more senses: kinesthetic sense, which is our awareness of our body’s dimensions and movement; vestibular sense, which is the awareness of the human’s balance and spacial orientation; and organic sense, which is the manifest of the internal organs (for example, hunger or thirst).
Pictures we take become a part of our legacy. Pictures of important days in our lives or just pictures of something that caught our attention is essential. As said on the Seedling Blog, “Photo-journaling our major life events is essential, but capturing the daily and mundane has equal importance” (The Importance of Photography). The little things that caught our attention give us much more insight into the kind of people we are than yet another cliche picture of the Eiffel Tower or a waterfall in Hawaii. Photos are a record of our lives, places we have been, things we have done, or who we used to be.
