Abstract— This correspondence addresses the use of a joint sourcechannel coding strategy for enhancing the error resilience of images transmitted over a binary channel with addit...
The compression of still images by means of the discrete wavelet transform (DWT), adopted in the JPEG-2000 and MPEG-4 standards, is becoming more and more widespread because it yie...
This paper proposes an image coding method based on adaptive downsampling which not only uses the pixel redundancy but also considers visual redundancy. At the encoder side, codec...
This paper proposes a new approach to combined spatial (Intra) prediction and adaptive transform coding in block-based video and image compression. Context-adaptive spatial predic...
A novel frequency-domain technique for image blocking artifact detection and reduction is presented in this paper. The algorithm first detects the regions of the image which presen...
