MEDICAL IMAGE ANALYSIS AND PROCESSING USING A DUAL TRANSFORM

Medical Image Analysis and Processing Using a Dual Transform

The demand for images in medical field has increased drastically over the years. The need for reducing the storage space has resulted in image compression. This paper presents a dual transform for medical image compression algorithm. The experimental results determines how the compression ratio (CR), peak signal to noise ratio (PSNR) and SNR (signal to noise ratio) of different compression algo...

Multiresolution image analysis using dual Fresnel transform pairs and application to medical image denoising

A new multi-resolution image analysis and image processing technique which split the band in the Fresnel transform signal domain has been proposed. There are two methods to solve the Fresnel integral equation. Applying two different Fresnel transform methods in invert direction to an image sequentially with an adequate distance parameter,a down-scaled image can be produced representing a multir...

Image processing by alternate dual Gabor frames

‎We present an application of the dual Gabor frames to image‎ ‎processing‎. ‎Our algorithm is based on finding some dual Gabor‎ ‎frame generators which reconstructs accurately the elements of the‎ ‎underlying Hilbert space‎. ‎The advantages of these duals‎ ‎constructed by a polynomial of Gabor frame generators are compared‎ ‎with their canonical dual‎.

Fragmentation measurement using image processing

In this research, first of all, the existing problems in fragmentation measurement are reviewed for the sake of its fast and reliable evaluation. Then, the available methods used for evaluation of blast results are mentioned. The produced errors especially in recognizing the rock fragments in computer-aided methods, and also, the importance of determination of their sizes in the image analysis ...
