Tumor microsphere profile detection method and device based on u-net network model

Abstract

The invention discloses a tumor microsphere contour detection method and device based on a U-net network model, and the method comprises the steps of training a built to-be-trained U-net network modelthrough a training image, and generating a trained U-net network model; in the to-be-trained U-net network model, except the last convolution block, connecting a residual structure behind each rest convolution block to sum the input image of the convolution block and the output image of the convolution block as the input image of the next convolution block; and generating an edge contour curve ofthe tumor microsphere image to be detected by using the trained U-net network model. The edge contour curve of the to-be-detected tumor microsphere image obtained in the method is obtained by using the trained U-net network model, the accuracy is higher, and the size of the tumor microsphere is calculated by using the edge contour curve subsequently, so that a calculation result with higher accuracy can be obtained.

Description

Technical field [0001] The present invention relates to a contour detection technology, and particularly relates to a tumor microsphere contour detection method and apparatus U-net network model. Background technique [0002] In the three-dimensional cell culture of tumor cells, it is necessary according to the growth and invasiveness of tumor cell detection, cytotoxicity study on the compound of the tumor cells. Based on this, the three-dimensional cell culture of tumor cells during tumor morphology requires the contour of the microspheres according to culture time culture, and measure the size of the recording, wherein the microspheres refers to the tumor sphere composed of a plurality of tumor cells, may be employed tumor area microspheres microspheres measure tumor size. [0003] The diameter of the prior art, according to the experimental incubation time will usually, the captured image microspheres tumor, then the tumor outline the contour of the edge of the image of the mi...
