The work including : ( 1 ) svm based auto detection and segmentation of left ventricle mri image the aim of the segmentation of the left ventricle mri image is to find out the inner and the outer contour of the left ventricle , while for that the structure of the heart is very complex , meantime the tag lines may also decay , the contrast of the object and the background will also descend , which still make the segmentation more difficult 同时，对核空间方法在图像处理领域的几种应用进行了论述。本文工作包括： ( 1 )设计基于svm的mri左心室图像的自动检测及分割过程心脏mri图像分割的目的是为了找出mri图像中左心室的内外轮廓，但是由于心脏的解剖结构非常复杂，再加上标记线会随时间衰减，目标和背景的对比度会下降，这使得图像的自动分割更加困难。
