In this paper we introduce an improved Canny edge detection algorithm and an edge preservation filtering procedure for asphalt concrete (AC) applications. Datasets of AC images were randomly selected to test this algorithm. Computer simulations show that the improved algorithm can make up for the disadvantages of Canny algorithm, detect edges of AC images effectively, and is a less time-consuming...
The prompt delivery of biomedical images for emergency diagnosis purpose is an important issue in health care organizations. This paper is aimed a developing class of algorithms to view and manipulate medical images on mobile devices and mainly PDA handhelds. We illustrate our method on human brain scans to view: 2-D single medical imaging scans, multi frames/slices medical imaging scans, internal...
In this paper we introduce a noise-resilient edge detection algorithm for brain MRI images. Also, an improved edge detection based on Canny edge detection algorithm is proposed. Computer simulations show that the proposed algorithm is resilient to impulsive noise which makes up for the disadvantages of Canny algorithm, and can detect more edges of MRI brain images effectively. Also, the concept of...
