Abstract

An image recognition method and an image recognition system can be applied to fetal ultrasound images. The image recognition method includes: (a) adjusting the image with a filter operator to decrease noise and to homogenize an image expression level of the pixel units within an individual object structure; (b) analyzing the image by a statistic information function, determining a foreground object pixel unit and a background pixel unit according to a max information entropy state of the statistic information function; and (c) searching by a profile setting value and recognizing a target object image among the foreground object pixel unit. The image recognition method can not only increase the efficiency of identifying the object of interests within the image and measuring the object of interests, but also improve the precision of measurements of the object of interests.
