Image Processing And Image Enhancement

imaging application. This is because the crucial data required for the classification phase are derived at this stage. Feature extraction is the process of estimating

DIGITAL IMAGES are electronic snapshots taken of a scene or scanned from documents, such as photographs, manuscripts, printed texts, and artwork. The digital image is sampled and mapped as a grid of dots or picture elements (pixels). Each pixel is assigned a total value (black, white, shades of gray or color), which is represented in binary code (zeros and ones). The binary digits ("bits") for each pixel are stored in a sequence by a computer and often reduced to a mathematical analog version for display or printing. http://preservationtutorial.library.cornell.edu/intro/intro-01.html

Digital Photography has become one of the most simplified and effective way of capturing and using the images. Digital images are very high in quality and also with the ease of viewing, editing and transferring it to any computers or mobile devices making it a very cost effective way of managing the images (Kornhaber, Betihavas, & Baber, 2015).

To learn about contrast enhancements, and the impact of the different enhancement types on raw imagery

In accession to the binary images, the proposed method may be tested on discrete color images also. These type of

In this world wherever your eyes can reach you will see pictures, videos and other type of graphics images. Images are used in everything from advertising in television and to promote your product in website so it is important to have better graphic images so it is clear and is not blurry and to make sure the graphic image is at its best there are many software and hardware tools we can use to make the graphic images better.

Digital modification of photos present in magazines or advertisements has become a habitual practice of 21st century photographers. The present work's purpose is to present an ambivalent account of the existing controversy surrounding photographic enhancement, by focusing on the artful or inspiring aspects together with analyzing its potentially harmful and dishonest nature.

It is used to correct defects illumination, eliminating noise and small spots and enhance the contours and contrast as much as possible without degrading the lesion.Preprocessing of the image is concerns with changing the colour image into gray scale image, removing the dark corners in the image and filtering to remove any artefacts in the image.

Texture is one of the crucial primitives in human vision and texture features have been used to identify contents of images. Examples are identifying crop fields and mountains from aerial image domain. Moreover, texture can be used to describe contents of images, such as clouds, bricks, hair, etc. Both identifying and describing characteristics of texture are accelerated when texture is integrated with color, hence the details of the important features of image objects for human vision can be provided. One crucial distinction between color and texture features is that color is a point, or pixel, property, whereas texture is a local-neighborhood property. The main motivation for using texture is the identifying and describing

In this report, I will talk about my understanding of the impact in various file format, the different compression techniques, and different resolutions and different colour depth. I will show print screens of different types of compression techniques, megapixels under image quality & resolution and three different types of colour depths. I will explain the reasons why some are larger compared to others. The format includes PSD, JPEG, TIFF, BMP and GIF. I will also go into detail why colour depths will affect the quality of the final output that the file has created.

Photography is a kind of visual art. In Wikipedia, art was defined as it is “expressing the author's imaginative or technical skill, intended to be appreciated for their beauty or emotional power”(3). Art is not simple reality; it is the beautiful pieces that artists put their creativity in and express their ideas. Applying this to photography, using Photoshop to edit pictures is an approach to paint on photos, just like using brush and pigments to paint on a painting. Unlike other kinds of visual art which artists may take a long time to finish, photography is all about the decisive moment. Most of decisive moments are not perfect, because photographers cannot control all the people and objects in the frame in that instant. Hence, if a photographer got a noteworthy photo with a little defect, one could edit the defect out the picture, and make it better express the photographer’s subject and approach to get the best results with Photoshop. Moreover, cameras people use today are not good as human eyes. For instance, human have much better dynamic range and sensitivity than cameras (4). Human easily observe things in the very bright and dark environment at the same time, but camera cannot. However, this issue can be simply solved by Photoshop. In addition, colors in the photos took by digital cameras have very many deviations on colors. Editing pictures can help people adjust the colors.

Manipulating a photo used to typically involve scissors, glue, and a high precision. The first photo manipulation meant that people actually had to move items around to create different photographic compositions. Nowadays, anyone with access to a computer can alter an image easily. But is important to understand the subject, the difference between photo retouch and photo manipulation. What is the difference? Photo retouch means changing the image to remove or repair damage or unwanted blemishes or objects. While photo manipulations means to change the photo with the purpose of altering its message or meaning. It involves transforming or altering a photograph using various methods and techniques in order to achieve desired results. Some photo manipulations are considered skilful artwork while others are considered as unethical, especially when used to deceive the public, such as making a product or person appear more pleasing to the

I know my audience very well in New Mexico and some areas in Arizona, as for the rest of the world, no, I have no idea. Just getting my work shown in New Mexico will keep me busy for a while and until I graduate I do not have the time to find out.

Other than the possible addition of a filter or internal add-on, most people will never need to surpass this step. However, at this stage nearly all professional photos sit only partially finished, still requiring at least some method of post-production editing. Used in a variety of ways, some photos only need slight adjustment to compensate for the colors or tones that the photographer could not fully reach in their original image. In contrast, whether removing unwanted blemishes or dulling a detracting color, some photographers require many revisions of editing to even come close to their desired product. Regardless of its extensiveness, the freedom to brush away any blemishes and fully accentuate the focal points allows post-production to serve as the vital finishing coat on a photographer’s

Digital manipulation of photos is a staple tool for almost all print, web, and digital designers. whether is be something they enjoy like a
