Identification method of abnormal cells in pathological sections based on multiscale expansion convolution

Abstract

The invention discloses an identification method of abnormal cells in pathological sections based on multiscale expansion convolution. The method comprises the steps of 1, preprocessing the electronically-scanned pathological sections to obtain training data; 2, setting up a multiscale expansion convolution division model, wherein a ResNeXt network serves as the basic framework of the model, ASPPmodules and DUC modules serve as the basic modules of the model, and number of the ASPP modules is 1 to 5; 3, adopting the training data obtained in step 1 to train the multiscale expansion convolution division model obtained in step 2, and adjusting parameters of the network according to a model predicting result and the overlap ratio of labels, so that the model is converged and the abnormal cells in the pathological sections are identified. By means of the identification method, the accuracy rate of sifting the abnormal cells is high, the sifting precision of the abnormal cells is high, andthe F1 value serves as an index of a measuring algorithm, and can reach 98% or above.

Description

technical field [0001] The invention belongs to the field of artificial intelligence, and in particular relates to a method for identifying abnormal cells in pathological slices. Background technique [0002] Abnormal cells in traditional pathological slides are screened manually: under the microscope, professional pathologists scan the entire slice with the naked eye through the movement of the slice to find whether there are abnormal cells in the entire slice. As the reading time increases, the error rate also increases. [0003] With the continuous development of technology, the identification of abnormal cells in pathological slides can be screened with the help of computers. Image semantic segmentation (Semantic Segmentation) is an important research direction of computer vision, and its task is to classify each pixel of a single image through computer algorithms. Semantic segmentation tasks have important applications in scenarios such as autonomous driving and objec...
