چکیده

In this paper we present a statistical modeling for DCT events frequency distribution for three images classes: landscape, portrait and document. We show that it is possible to fit a mathematical model capturing the underlying statistical distribution. This modeling allows us to automatically generate optimized Huffman tables for each quality factor involved in the compression engine.

Image Compression using hybrid of DWT,DCT and Huffman Coding

This research paper presents a proposed method for the compression of medical images using hybrid compression technique (DWT, DCT and Huffman coding). The objective of this hybrid scheme is to achieve higher compression rates by first applying DWT and DCT on individual components RGB. After applying this image is quantized to calculate probability index for each unique quantity so as to find ou...

An efficient and scalable 2D DCT-based feature coding scheme for remote speech recognition

A 2D DCT-based approach to compressing acoustic features for remote speech recognition applications is presented. The coding scheme involves computing a 2D DCT on blocks of feature vectors followed by uniform scalar quantization, run-length and Huffman coding. Digit recognition experiments were conducted in which training was done with unquantized cepstral features from clean speech and testing...

An Upper Limit of AC Huffman Code Length in JPEG Compression

A strategy for computing upper code-length limits of AC Huffman codes for an 8x8 block in JPEG Baseline coding is developed. The method is based on a geometric interpretation of the DCT, and the calculated limits are as close as 14% to the maximum code-lengths. The proposed strategy can be adapted to other transform coding methods, e.g., MPEG 2 and 4 video compressions, to calculate close upper...

Low-Complexity Scalable DCT Image Compression

We have developed a scalable image compression scheme with a good performance-complexity trade-off. Like JPEG, it is based on the 8 × 8 block discrete cosine transform (DCT), but it uses no additional quantization or entropy coding (such as Huffman or arithmetic coding). Bitrate or quality scalability is enabled by encoding the DCT coefficients bit plane by bit plane, starting at the most signi...

A novel technique for image steganography based on Block-DCT and Huffman Encoding

Image steganography is the art of hiding information into a cover image. This paper presents a novel technique for Image steganography based on Block-DCT, where DCT is used to transform original image (cover image) blocks from spatial domain to frequency domain. Firstly a gray level image of size M × N is divided into no joint 8 × 8 blocks and a two dimensional Discrete Cosine Transform(2-d DCT...
