Abstract: In the present time of sight and sound, the necessity of picture/video stockpiling and video playback, transmission for video conferencing, picture and video recovery and so forth are expanding exponentially. Thus, the need of better pressure innovation is consistently popular. Present day applications, notwithstanding high pressure proportion, additionally interest for proficient encoding and deciphering forms, with the goal that computational imperative of some continuous applications is fulfilled. Two broadly utilized spatial space pressure systems are discrete wavelet transform and multi-level block truncation coding (BTC). DWT method is used to stationary and non-stationary images and applied to all average pixel value of image. Muli-level BTC is a kind of lossy picture pressure strategy for greyscale pictures. In this,the unique picture is partitioned into squares and after that uses a quantizer to decrease the quantity of dark levels in each square while keeping up a similar mean and standard deviation. In this paper is studied of Multi-level BTC and DWT technique for gray and color image.
