A pattern-based lossy compression scheme for document images
نویسندگان
چکیده
CDIS is a pattern based, nearly lossless compression system for scanned document images. In this paper, we introduce a hierarchical lossy pattern instance position coding technique which results in a significant improvement in compression with no visible artifacts. CDIS codes text positions by automatically formatting blocks of text, then transmitting the position errors for each pattern. Lossy coding is achieved by coding errors in reduced precision, subject to quality guarantees.

Compression can be done by lossy or lossless methods. The lossy methods have been used more widely than the lossless compression. Although, many methods for image compression have been proposed yet, the methods using intelligent skipping proper to the visual models has not been considered in the literature. Image inpainting refers to the application of sophisticated algorithms to replace lost o...
متن کاملLossy compression of gray-scale document images by adaptive-offset quantization
This paper describes an adaptive-offset quantization scheme and considers its application to the lossy compression of grayscale document images. The technique involves scalar-quantizing and entropy-coding pixels sequentially, such that the quantizer’s offset is always chosen to minimize the expected number of bits emitted for each pixel, where the expectation is based on the predictive distribu...
متن کاملBPCS steganography using EZW lossy compressed images
This paper presents a steganography method based on an embedded zerotree wavelet (EZW) compression scheme and bit-plane complexity segmentation (BPCS) steganography. The proposed steganography enables us to use lossy compressed images as dummy files in bit-plane-based steganographic algorithms. Large embedding rates of around 25% of the compressed image size were achieved with little noticeable...
متن کاملA pattern matching approach to image compression
We propose an image compression scheme based on approximate pattern matching, that we name Pattern Matching Image Compression (PMIC). We give new, eecient algorithms for performing computations motivated by this scheme, and describe the compression ratios experimentally obtained. The main idea is a lossy extension of the Lempel-Ziv data compression scheme in which one searches for the longest p...
متن کاملPattern Matching Image Compression with Predication Loop: Preliminary Experimental Results
Recently, a novel image compression technique based on pattern matching was proposed, namely Pattern Matching Image Compression (PMIC). Basically, it is a lossy extension of the well known Lempel-Ziv scheme. It was proved that such an extension leads to a suboptimal compression, and that the compression ratio can as low as the so called R enyi entropy. Success of PMIC crucially depends on sever...
