چکیده

In this earlier multimedia scenario, the various disputes are the optimized use of storage space and also bandwidth. In order to shrink the storage space of pictures and transmission of information with customize limited bandwidth availability, Image compression plays a crucial role by retreating the size of image and to exploit the bandwidth in economical and valuable manner without demeaning the superiority of image. In this paper we explore the review of different compression of images with their pros and cons. The overall compression process helps to reach a satisfactory level for image transmission in limited bandwidth over a telecommunication medicine application. We analyzed the performance of image compression technique using quality metrics such as Peak Signal to Noise Ratio (PSNR), Mean Square Error (MSE) and Compression Ratio (CR). The obtained results show that local threshold provides better reconstruction of image than Global threshold. Index words: Mean Square Error (MSE), Compression Ratio (CR), Peak Signal to Noise Ratio (PSNR), Threshold

A Survey on Lossless Compression of Bayer Color Filter Array Images

Although most digital cameras acquire images in a raw format, based on a Color Filter Array that arranges RGB color filters on a square grid of photosensors, most image compression techniques do not use the raw data; instead, they use the rgb result of an interpolation algorithm of the raw data. This approach is inefficient and by performing a lossless compression of the raw data, followed by p...
