Lossless image compression retains the same image after compression .The proposed method is adaptive, not taking complete image but accessing row major order of the block of the image to reduce the size of the pixel and adaptive transmit the pixel data at receiver side and at the same side simultaneously decode the pixel and display the same pixel. In this method we use a concept of dynamic allocation for generating variable length of each pixel after subtracting from the original pixel as a maximum intensity pixel in the block .In the proposed method, one can adaptively select either row wise or column wise scan within a block of a matrix. This method can be applied on grey scale images.
