Zero-thresholding of KH and KJ sign images for multiple scale segmentation of surfaces
نویسنده
چکیده
This paper compares the KH and KJ sign images in the context of the zero-thresholding at single and multiple scales. It points out that consistent zero-thresholding of curvatures remains necessary for multiple scale surface segmentation. Even though KJ sign image is a good choice for single scale surface segmentation with a zero-thresholding formula J = K , the KH sign image is a better choice for multiple scale surface segmentation, whose zero-thresholding formula K 2jHj H + 2 H maintains eeectiveness for both KH and KJ sign images.

Robust Potato Color Image Segmentation using Adaptive Fuzzy Inference System
Potato image segmentation is an important part of image-based potato defect detection. This paper presents a robust potato color image segmentation through a combination of a fuzzy rule based system, an image thresholding based on Genetic Algorithm (GA) optimization and morphological operators. The proposed potato color image segmentation is robust against variation of background, distance and ...
متن کاملIris localization by means of adaptive thresholding and Circular Hough Transform
In this paper, a new iris localization method for mobile devices is presented. Our system uses both intensity and saturation threshold on the captured eye images to determine iris boundary and sclera area, respectively. Estimated iris boundary pixels which have been placed outside the sclera will be removed. The remaining pixels are mainly the boundary of iris inside the sclera. Then, circular ...

متن کاملReducing Light Change Effects in Automatic Road Detection
Automatic road extraction from aerial images can be very helpful in traffic control and vehicle guidance systems. Most of the road detection approaches are based on image segmentation algorithms. Color-based segmentation is very sensitive to light changes and consequently the change of weather condition affects the recognition rate of road detection systems. In order to reduce the light change ...
