Abstract

The present application discloses a cast recognition method and a cast recognition method device, and a urine analyzer. The method comprises the following steps: an image acquisition step, for acquiring an input image to be processed; a segmentation step, for segmenting a current-level image, to generate a first image indicating cast candidates, wherein in an initial state, the current-level image is the input image; and a classification step, for calculating multiple features for each cast candidate separately on the basis of the first image and/or a grayscale image of the current-level image, and classifying each cast candidate on the basis of the multiple features so as to determine whether it is a cast. The technical solution of the present application can increase the precision of cast recognition.
