The inventive concepts herein relate to performing block retrieval on a block to be processed of a urine sediment image. The method comprises: using a plurality of decision trees to perform block retrieval on the block to be processed, wherein each of the plurality of decision trees comprises a judgment node and a leaf node, and the judgment node judges the block to be processed to make it reach the leaf node by using a block retrieval feature in a block retrieval feature set to form a block retrieval result at the leaf node, and at least two decision trees in the plurality of decision trees are different in structures thereof and/or judgments performed by the judgment nodes thereof by using the block retrieval feature; and integrating the block retrieval results of the plurality of decision trees so as to form a final block retrieval result.

Method and apparatus for performing block retrieval on block to be processed of urine sediment image

Concepts herein relate to processing urine sediment images. An example method comprises: approximating the color of a pixel in a block to be processed to one of the kcolors in a code book, wherein the code book is a set of the kcolors generated in a set of urine sample blocks; obtaining a distribution histogram of the number of pixels the color approximation results of which fall on each color of the kcolors; using an occurrence frequency correction factor to correct the number of pixels the color approximation results; standardizing the corrected number of pixels the color approximation results; and processing the block to be processed.
