Image Compression Using Advanced Optimization Algorithms
—In this paper, a new image compression technique that uses three-dimensional Discrete Cosine Transform and relies on Two-Dimensional Discrete Wavelet Transform, for image classification, is proposed. The proposed technique utilizes a modified quantization table and a method for converting a three-dimensional image cube into a onedimensional array, which provides better coding efficiency in th...
متن کاملOptimization of Image Compression algorithms using DWT- DCT method
Information is generated at very high speed in today’s Digital Era. Images have vast share in Information generated, so it’s important to reduce the image file size for storage and effective communication. Image compression technique helps in reducing storage and bandwidth requirement for transmission. Optimization of Image compression algorithms is the basic crux of this paper. DCT is most pop...
متن کاملImage Compression Using Optimization Techniques
The FIC is one of our attempts towards the design of robust fractal image compression. The main disadvantage of FIC is the high computational cost. To overcome this drawback, the technique described here utilizes the optimization techniques, like GA, ACO and PSO which greatly decreases the search space for finding the self similarities in the given image. FIC is robust against outliers in the i...
متن کاملIntelligent 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 کاملCompression of Image Contours using Combinatorial Optimization
Compression of image contours is an important problem in many contexts. An example is object oriented video coding, where eecient encoding of shape information of arbitrarily shaped objects is a major problem. This paper presents a method for compressing contours by extracting representative points from the original curve. By formulating the point selection problem as a graph theory problem, kn...
