Detection and Recognition of the surface roughness in the images is a topic which has received a lot of attention in the field of image processing. In this paper, a new noncontact measurement method of surface roughness, by texture analysis, is developed based on Charge Coupled Device (CCD) image in planning operations. Firstly, the surface image of the workpieces is acquired using the A102f CCD digital...
In this paper, a statistical texture modeling method is proposed for medical volumes. As the shapes of the human organ are very different from one case to another, 3D volume morphing is applied to normalize all the volume datasets to a same shape for removing shape variations. In order to deal with the problems of high-dimension and small number of medial samples, we propose an effective image compression...
This paper presents an improved Mean Shift tracking algorithm. It extends the classic Mean Shift tracking algorithm by combining color and texture features. In the proposed method, firstly, both the color feature and the texture feature of the target are extracted from first frame and the histogram of each feature is computed. Then the Mean Shift algorithm is run for maximizing the similarity measure...
A fast and efficient approach to color image segmentation and texture feature extraction is developed. In the proposed image segmentation algorithm, a new quantization technique for HSV color space is implemented to generate a color histogram and a gray histogram for K-Means clustering, which operates across different dimensions in HSV color space. Then a texture feature extraction method for content-based...
Image warping and morphing are important visual effect tools in entertainment industry and other research fields. We developed a prototypical automatic facial image manipulation system (AFIM) for face morphing and shape normalization (warping). In our AFIM system, there are two main functions: (1) warping a facial image to a target image (face shape normalization), (2) generation of inter- or intra-personal...
This paper describes a fast and efficient texture feature extraction method based on image segmentation in HSV color space, which is especially useful in resource-limited embedded systems. In this approach, a query image is first segmented based on its color feature, and the proposed technique is applied on the labeled image to efficiently extract texture feature. Compared with the feature extraction...
In this paper, a new method for eye gaze tracking is proposed under natural head movement. In this method, pixel-pattern-based texture feature (PPBTF) is proposed to calculate the infrared eye features according to the characteristic of the infrared eye, and a new binocular vision approach is adopted to detect the space coordinate of the eye. The combined features of space coordinates and PPBTF features...
