In this paper, we presented a structure-adaptive B-snake model for segmenting the complex structures in medical images. A strategy of automatic control-point insertion, adaptive to the structure of the studied object, has been proposed. Furthermore, a method of &mum mean square energy (MMSE) is developed to iteratively estimate the position of those control points in the B-snake model. By apply...

This paper presents an object contour detection using the object shape model. First, we detect the change of background luminance ratio outside the bounding box of object. Second, the temporal segmentation is obtained by mesh based motion activity detection. A new combined mask is composed of temporal segmentation result and shape model by OR operation. Finally, for modification of the mask, we...

In this paper, we propose a wavelet analysis based piecewise linear stylization of the pitch trajectory. We also address the often-faced difficulty in handling the tradeoff between mean squared error and the number of lines used for fitting, where a heuristic approach is typically used to make the stylization choice. We pose the piecewise linear stylization task as a minimization problem by def...

line no. 4 was selected from local champ a rice of lord egan, based on pure line selection method, during 1992 to 1995. the mean yield of this line was 6342 and 6829 kgha-l in two regions of lord egan in 1996 to 1997. the yield of this line was 700-1500 kgha-l more than that of lord egan local rice. line 4 is more early maturing than the local rice with better marketability and quality. amylase...

in this research the effect of two different methods of carcass chilling (immersion and evaporative) in the poultry industrial slaughter line on microbial load and carcass weight changes was studied. for sampling, after evisceration, each carcass weighted and rinsed with 250 ml of sterile water in a plastic bag. 25 ml of rinses water was taken and into sterile scaled container sent to laborator...
