This paper addresses the issue of face and lip tracking via chromatic detector, CCL algorithm and canny edge detector. It aims to track face and lip region from static color images including frames read from videos, which is expected to be an important part of the robust and reliable person identification in the field of computer forensics. We use the M2VTS face database and pictures took from ...

We apply our proposal method (Canny_PCA_ANN) for recognition of six basic facial expressions on JAFFE database consisting 213 images posed by 10 Japanese female models. The experimental result shows the feasibility of our proposal method.

Potholes are a nuisance, especially in the developing world, and can often result in vehicle damage or physical harm to the vehicle occupants. Drivers can be warned to take evasive action if potholes are detected in real-time. Moreover, their location can be logged and shared to aid other drivers and road maintenance agencies. This paper proposes a vehicle-based computer vision approach to iden...

This paper attempts to quantify the trade-oos that exist among the number of ngers, coeecient of friction and the goodness of a grasp. In particular, we give a general framework for deening a grasp metric that takes friction into account. We contrast our approach to an older metric that was proposed by Ferrari and Canny FC92] for the frictional case. In addition, we discuss several algorithmic ...

In model based image interpretation the cue generation process must be robust; i.e. able to generate appropriate cues for wide variety of objects. In this work we describe a model-based approach to cue generation and demonstrate its operation on both synthetic test data and natural images of epithelial cells. Epithelial cells were chosen because their appearance is highly variable. Statistical ...

Canny algorithm can be used in extracting the object’s contour clearly by setting the appropriate parameters. The Otsu algorithm can calculate the high threshold value which is significant to the Canny algorithm, and then this threshold value can be used in the Canny algorithm to detect the object’s edge. From the exprimental result, the Otsu algorithm can be applied in choosing the threshold v...

Camouflage is an attempt to make a target "invisible" by making the target appearance blend into the background. Camouflage related work is typically either in camouflage assessment and design or in camouflage breaking. This paper will discuss two current methods of camouflage breaking. Camouflage breaking is important because of the obvious military tactics, background subtraction, and general...

In this paper, we propose a novel method for feature detection of an object by fusion of range and intensity images. For this purpose, we have developed a data acquisition system with a laser source and camera interfaced with Silicon Graphics machine. 3-D mesh representation of the surface of the object is obtained from the acquired range images. Extraction of structural features from the range...

In image processing edge detection is an essential topic. We propose a new method for a simple edge detection and fast computation using fuzzy logic rule .We compare proposed edge detector to other existing edge detectors such as sobel edge detector, canny edge detector, and prewit edge detector. In addition it also deblurred the images efficiently and effectively. We present a new image deblur...
