introduction: in patients with cardiac artery disease, a myocardial perfusion scan, which is a non-invasive method, is utilized. this study is conducted to develop an advantageous software applicable to quantitative myocardial spect perfusion. material and methods: each cross-section of the left ventricle was segmented by applying a fuzzy clustering method. after obtaining the myocardial skelet...

Application with sequential algorithm can no longer rely on technology scaling to improve performance. Image processing applications exhibits high degree of parallelism and are excellent source for multicore platform. Major challenge of parallel processing is not only aim to high performance but is to give solution is less time and better utilization of resources. This paper focus on calculatin...

Today, real-time processing has become a stipulation in all practical fields especially in image processing. This paper presents an experimental comparison of implementation of Niblack’s Algorithm, a binarization algorithm for image-processing in Visual C++ using OpenCV library with its implementation on FPGA. It aims at addressing the real-time processing scenario and how to overcome the situa...

‎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.

improving the quality of medical images at pre and post-surgery operations are necessary for beginning and speeding up the recovery process. partial differential equations (pdes)-based models have become a powerful and well known tool in different areas of image processing such as denoising, multiscale image analysis, edge detection and other fields of image processing and computer vision. in t...

Today image steganography plays a key role for exchanging a secret data through the internet. However, the optimal choice of images formats for processing steganography is still an open issue; therefore, this research comes into a table. This research conducts a comparative study between Scalable Vector Graphics (SVG) image format and Portable Network Graphics (PNG) image format. As results sho...

Histograms are the basis for numerous spatial domain image processing techniques. Histogram manipulation can be used effectively for image enhancement. In addition to providing image statistics, the information inherent in the histogram is also quiet useful in other image processing applications, such as image compression and segmentation. Histograms are simple in manipulation as well as econom...
