A novel method for progressive image transmission using blocked wavelets
نویسندگان
چکیده
The techniques of progressive image transmission (PIT) divide image delivery into several phases. PIT’s main objective is to efficiently and effectively provide an approximate reconstruction of the original image in each phase. Therefore, this study proposes the Blocked Wavelet Progressive Image Transmission method (BWPIT) based on the wavelet transformation and the spatial similarity of pixels, to reduce the bit-rate and increase the image quality in an early phase of progressive image transmission. Experimental results show that the transmission bit-rate and the image quality of BWPIT are significantly better than those of BPM, IBPM, and WbPIT in each early phase.

Intelligent scalable image watermarking robust against progressive DWT-based compression using genetic algorithms
Image watermarking refers to the process of embedding an authentication message, called watermark, into the host image to uniquely identify the ownership. In this paper a novel, intelligent, scalable, robust wavelet-based watermarking approach is proposed. The proposed approach employs a genetic algorithm to find nearly optimal positions to insert watermark. The embedding positions coded as chr...
