background: breast cancer is one of the most important diseases in females. malaysian women have not excluded. according to the malaysian oncology society [1], about 4% of women (who are 40 years old and above) have involved by breast cancer. masses and microcalcifications are two important signs for breast cancer diagnosis on mammography. according to our estimation, radiologists could diagnos...

image completion is one of the subjects in image and video processing which deals with restoration of and filling in damaged regions of images using correct regions. exemplar-based image completion methods give more pleasant results than pixel-based approaches. in this paper, a new algorithm is proposed to find the most suitable patch in order to fill in the damaged parts. this patch selection ...

anomaly detection (ad) has recently become an important application of hyperspectral images analysis. the goal of these algorithms is to find the objects in the image scene which are anomalous in comparison to their surrounding background. one way to improve the performance and runtime of these algorithms is to use dimensionality reduction (dr) techniques. this paper evaluates the effect of thr...

in many autonomous mobile applications, robots must be capable of analyzing motion of moving objects in their environment. duringmovement of robot the quality of images is affected by quakes of camera which cause high errors in image processing outputs. in thispaper, we propose a novel method to effectively overcome this problem using neural networks and kalman filtering theory. thistechnique u...

introduction breast cancer is one of the most life-threatening conditions among women. early detection of this disease is the only way to reduce the associated mortality rate. mammography is a standard method for the early detection of breast cancer. today, considering the importance of breast cancer detection, computer-aided detection techniques have been employed to increase the quality of ma...

Noise removal operation is commonly applied as pre-processing step before subsequent image processing tasks due to the occurrence of noise during acquisition or transmission process. A common problem in imaging systems by using CMOS or CCD sensors is appearance of  the salt and pepper noise. This paper presents Cellular Automata (CA) framework for noise removal of distorted image by the salt an...

Image zooming is one of the current issues of image processing where maintaining the quality and structure of the zoomed image is important. To zoom an image, it is necessary that the extra pixels be placed in the data of the image. Adding the data to the image must be consistent with the texture in the image and not to create artificial blocks. In this study, the required pixels are estimated ...

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 ...
