Abstract

Useful image compression to compress the file size of the image thus saving storage and speed up the transfer process. This study aims to measuring on the quality of the image as compressed by instant messenger application by comparing the initial image or the input image with the image compression results. The assessment is based on objective criteria by using research methods of comparative research. The objective criteria used is the compression ratio, PSNR, the quality index, and SSIM. From this research it is known that each - each instant messenger applications have a compression ratio that varies. In addition, PSNR, SSIM, and quality index are different too. From the analysis concluded that the order of the image that has a fairly high compression ratio and good quality is the Line

Abstract

In the film world greenscreen or bluescreen is already widely in use as a background making technology . Utilization of this technology is very great because filmmakers can imagine changing the background to the shape or the desired atmosphere without having to perform image capture directly to the location . Chroma key is a technique for combining two images made with a video camera as well , in which a background color of an image to remove (made transparent ) , was replaced by another image behind it. Deficiencies that exist in the chroma key is that at the time of editing of the hair . Here the author tries to do research on how to minimize the weaknesses mengilangkan edge portion of hair at the time of editing green screen by optimizing lighting / lighting .
