A user friendly image sharing scheme using JPEG-LS median edge predictor

This work attempts to calculate the differences between pixels in a block by using the JPEG-LS median edge predictor. Given the role of this predictor, the generated differences refer to both the left pixel and its neighboring pixels, thus diminishing the values of differences and enhancing the reconstructed image quality. Experimental results demonstrated the effectiveness of using the JPEG-LS median edge predictor.
