A resolution enhancement scheme is presented. It consists of interpolation followed by processing with an adaptive nonlinear forward-and-backwarddi usion process that enhances edges while suppressing interpolation ringings and denoising smooth areas. keywords: super-resolution, image interpolation, anisotropic di usion, image enhancement, scale-space.

Image mining deals with the extraction of image patterns from a large collection of images. Clearly, image mining is different from low-level computer vision and image processing techniques because the focus of image mining is in extraction of patterns from large collection of images, whereas the focus of computer vision and image processing techniques is in understanding and / or extracting sp...

‎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.

Abstract—In modern days, Image processing is now of utmost importance, especially in real-time scenarios where errors contemporaneous image could have disastrous results; the research and analysis methods real- time istherefore extraordinary importance. Real-time methodologies are consequently significance. This article's main aim to provide an overview currentstate (Applications), useful metho...

In this paper, we present a Medical Image Visualizer (MIV) targeting cardiac SPECT images. The visualizer is built fully on open source image processing and visualization software. The main features of the visualizer are: a semiautomatic procedure for segmenting challenging cardiac images and an implementation of the polar map visualization (Bull’s eye diagram) that follows recent recommendatio...

Three-dimensional ultrasound computer tomography is a new imaging method for early breast cancer diagnosis. It promises reproducible images of the female breast in a high quality. However, it requires a time-consuming image reconstruction, which is currently executed on one PC. Parallel processing in reconfigurable hardware could accelerate signal and image processing. This paper evaluates the ...

purpose: to present a new reliable and accurate iris recognition method applicable in identification systems. methods: the system was implemented and tested on 876 standard iris images (daugman iris images database) from 876 persons of different nationalities via image processing techniques. results: false accept reject (far) and false reject reject (frr) were smaller in our suggested method as...

The key obstacle to communicating images over wireless sensor networks has been the lack of suitable processing architecture and communication strategies to deal with the large volume of data. High packet error rates and the need for retransmission make it inefficient in terms of energy and bandwidth. This paper presents novel architecture and protocol for energy efficient image processing and ...

This paper shows how to solve the recognition of ultrasound brain-stem images. Our work is based on PCA method that is very useful and known method for image processing. We will demonstrate a solving with C# application, Gnumeric spreadsheet as a standard solution. Also we will use an artificial neural networks (ANN) for this problem and we will compare a results. The ANN are generally very usa...

A welded structure must be inspected to guarantee that the weld quality meets the design requirements to assure safety and reliability. However, X-ray image analyses and defect recognition with the computer vision techniques are very complex. Most difficulties lie in finding the small, irregular defects in poor contrast images which requires pre processing to image, extract, and classify featur...
