Sample-guided progressive image coding
نویسندگان
چکیده
We introduce a low-level image representation using local orientation on a steerable pyramid. Its performance is demonstrated for a purposively progressive image coder which transmits and reconstructs parts of an image guided by their similarity to a given sample image. Like human visual attention, the image is scanned in a most-importantfirst order to gain a maximum of visual information with minimum code.

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...

متن کاملAdaptive Progressive Coding for Compression of Bi-level Video Images
In video compression, progressive coding plays an important role in terms of coding efficiency and error resilience and has been an attractive research topic since the standardization of H.264/AVC. In this paper, we propose a high-performance progressive coding scheme with the help of bi-level images. Different from progressive H.264/AVC and other video standards, we construct image epitomes as...
متن کاملStatistical properties of coded interlaced and progressive image sequences
In this paper, we investigate the statistical properties of interlaced and progressive image sequences in order to determine what is the most efficient format from a coding point of view. Intra- and inter-coding modes are both considered. The main result is that, for both intra- and inter-images, the coding of progressive images outperforms the coding of interlaced ones for low bit rates and la...
