An entropy minimization histogram mergence scheme and its application in image compression

作者：

Highlights：

• An preprocessing method for image compression, i.e., EMHM is proposed.

• EMHM can reduce image entropy and number of grayscale with nonzero pixel population.

• Based on our EMHM, the performance of JPEG, JPEG2000, and BPG can be improved.
