Objective To compare the diagnostic differences between digitized sectional image(PDSI) and CT manifestation on lung contusion in pigs.

A 3D data field was constructed out of the sectional image stack through linear interpolation, and a seeded region growing algorithm was adopted for the objective tissue segmentation.

Reconstruction of 3D CAD models based on tooth s cross-sectional images;

Researches the new techniques of three-dimensional(3D) reconstruction and segmentation, display and analysis on series slices of images including microscopic wide field optical sectioning by the deconvolution method and Cryo-electron microscope slices by electron tomography(ET) and series of computed tomography(CT).

Based on the authors practical experience,this paper describes a method for determining the resolving power of digital image and the dimensions of output print picture according to the input format size in pixels,by using software Photoshop6.

To put forward a new segmentation method in tumour immunohistochemical pathological image,we set up the first segmentation model of gray distribution information and find different coloration region according to the characteristics of tissue gray distribution in pathological images.

Objective To identify typical pathological images by using the neural network based on cross-entropy method.
