چکیده
In the survey of the activity of the kidneys by nuclear medical imaging, determining the region of interest (ROI) by the operator is an important factor. The current study aimed to obtain an automatic method to determine the ROI of kidney to reduce the error of manual method of the operator. In this survey, the equations obtained through the thresholding method are performed to semi-automation of ROI drawing. For the left kidney the threshold is 1.03 times the mean count of left kidney and for the right kidney, the good threshold is 1.08 times the mean court of the right kidney with correlation coefficient 0.95.

متن کاملA FUZZY DIFFERENCE BASED EDGE DETECTOR
In this paper, a new algorithm for edge detection based on fuzzyconcept is suggested. The proposed approach defines dynamic membershipfunctions for different groups of pixels in a 3 by 3 neighborhood of the centralpixel. Then, fuzzy distance and -cut theory are applied to detect the edgemap by following a simple heuristic thresholding rule to produce a thin edgeimage. A large number of experime...

Edge Detection is an important task for sharpening the boundary of images to detect the region of interest. This paper applies a linear cellular automata rules and a Mamdani Fuzzy inference model for edge detection in both monochromatic and the RGB images. In the uniform cellular automata a transition matrix has been developed for edge detection. The Results have been compared to the ...

متن کاملFully automatic lesion boundary detection in ultrasound breast images
We propose a novel approach to fully automatic lesion boundary detection in ultrasound breast images. The novelty of the proposed work lies in the complete automation of the manual process of initial Region-of-Interest (ROI) labeling and in the procedure adopted for the subsequent lesion boundary detection. Histogram equalization is initially used to preprocess the images followed by hybrid fil...
