Flowchart of automatic cervical cell screening algorithm. a Flowchart of conventional cellular image analysis segmentation is usually the precondition of classification. b Flowchart of the algorithm proposed in this paper to improve the accuracy and efficiency, the segmentation is omitted, and the block-based processing algorithm is adopted. The images were divided into blocks, and then features of three color models were analyzed. An SVM classifier was adopted to build a model and to classify the blocks into normal and abnormal. The output was the suspicious blocks
