    A Simplified Fractal Texture Analysis Approach using Quadtree Decomposition with Huffman Coding Technique 2021 September
    (Middle East Journal of Applied Science & Technology, 2021) Jacob, Rani
    Fractal compression is compression of the lossy type, which is applied for natural textured images. A fractal image compression technique based on the Quadtree algorithm and Huffman coding is proposed in this work. Agonizingly, the term "fractal compression" refers to an image compression technique that uses the fractal geometry of the image data stream to achieve lossy compression. Realistic images and textures are created with the help of this tool. It is based on the fact that parts of an image are frequently similar to other parts of the same image, which allows for faster processing. The most widely used partitioning mechanism is image partitioning in a tree structure. In this emerging world of image processing, quad tree partitioning is a one-of-a-kind technique that divides an image into a set of homogeneous regions. Huffman coding is a type of data compression that is lossless. The Huffman encoding algorithm is introduced through this technique, which creates an alphabetic list of all of the alphabet symbols, which is then arranged in descending order of their likelihood of occurring. The peak signal-to-noise ratio is quite improved by employing the proposed technique, and the encoding time is reduced.

    An Efficient Analysis of Wavelet Techniques on Image Compression
    (Irish Interdisciplinary Journal of Science & Research (IIJSR), 2022) Jacob, Rani
    Compression can be defined as an art form that involves the representation of information in a reduced form when compared to the original information. Image compression is extremely important in this day and age because of the increased demand for sharing and storing multimedia data. Compression is concerned with removing redundant or superfluous information from a file to reduce the size of the file. The reduction of the file size saves both memory and the time required to transmit and store data. Lossless compression techniques are distinguished from lossy compression techniques, which are distinguished from one another. This paper focuses on the literature studies on various compression techniques and the comparisons between them.

    Impeccable MRI Image Compression with Non-Uniform Partition and U-System
    (International Journal of Creative Research Thoughts (IJCRT), 2022) Jacob, Rani
    In MRI digital images have multivariate texture complexities, there is a need for a compression algorithm that is effective in the compression of such images with improved quality of the compressed image and successfully reduced blocking artifacts. This paper gives an efficient algorithm that compresses an MRI image by dividing the image into 8×8 high texture image blocks then 16×16 low texture image blocks using image texture adaptive non-uniform rectangular partition and a transform coding blocking of different sizes which finally uses a flexible adaptive quantization scheme while considering human visual system (HSV). The algorithm discussed in this paper is more efficient than the DCT algorithm and is more tolerant to low bit rate images create the compressed image to a high quality and conquer all the potential blocking artifacts that develop with DCT algorithm image compression.
