Abstract

Image compression is aimed to reduce the irrelevance and redundancy of the image data for the purpose to store or transmit data in an efficient form. A Novel image compression technique is proposed which integrates parameter-assistant inpainting (PAI) to exploit visual redundancy in colour images. In this approach, an input image at the encoder side is divided into featured and non-featured regions at block level. The featured blocks matching the predefined model class are coded by a few parameters, whereas the non-featured blocks are coded traditionally. At the decoder side, the featured regions are restored through PAI which is relying on both delivered parameters and surrounding information. Experimental results show that the proposed method outperforms JPEG in featured regions by an average bit rate saving of 73% at similar perceptual quality levels.
