Performing image acquisition and processing can require a high amount of computational resource. In this article, I am discussing the application Canny Edge Detection algorithm to live webcam real-time using NI’s software environment.

Image Edge Detection is one of the most important parts of image processing. In this paper, by fuzzy technique, a new method is used to improve digital image edge detection. In this method, a 3x3 mask is employed to process each pixel by means of vicinity. Each pixel is considered a fuzzy input and by examining fuzzy rules in its vicinity, the edge pixel is specified and by utilizing calculatio...

In this paper a new approach for blurred image restoration is presented. Our algorithm is based on human vision which zooms back and forth in the image in order to identify global structures or details. Deconvolution parameters are estimated by an edge detection and correspond to the ones of a chosen edge detection model. The segmentation is obtained by merging multiscale information provided b...

The important step of image processing is edge detection .Conventionally, the method of edge detection only provides the information regarding edges from certain aspects. In this paper, detection of edges is done using multi structural elements with the help of morphological operations and then analyses the results with the help of different parameters. By simulation and comparing the images wi...

Currently, magnetic resonance imaging (MRI) has been utilized extensively to obtain high contrast medical image due to its safety which can be applied repetitively. To extract important information from an MRI medical images, an efficient image segmentation or edge detection is required. Edges are represented as important contour features in the medical image since they are the boundaries where...

The Intelligence of Human-Computer Interaction is one of the hot researching areas. Facial expression recognition is an important part of human-computer interaction. At present, the research of facial expression recognition has entered an era of a new climax. In real-time facial expression recognition system, the paper presents an expression feature extraction method that combined canny operato...

Edge detection is a primary function in image processing. It is the name for a set of mathematical methods which aim at identifying points in a digital image at which the image brightness changes sharply or, more formally, has discontinuities. In this paper we are going to have a short introduction to edge detection basic concepts and continue with 2 popular methods: Canny edge detection and Ga...
