Problems solved by technology
However, in the process of identifying the sample area, due to the poor light transmittance of the section coverslip boundary, which is just similar to the light transmittance of the sample area, the boundary of the cover glass cannot be well identified and removed by the threshold.
The method of manual border removal will seriously affect the efficiency of scanning slices
[0004] In the traditional method of slide identification, there will be a large number of coverslip positions, which need to be deleted manually; if the positions of the coverslips are not deleted, they will also be regarded as scanned tissue areas, which will increase the corresponding scanning time. At the same time, a large amount of unnecessary data is stored in the file; the doctor will also see the redundant part when looking at the digital pathology slide, which affects the pathologist's reading of the slide

The invention discloses a method and a device for removing a cover glass boundary in a digital slice scanner. The method comprises the following steps: acquiring an original slice navigation preview;performing binarization processing on the slice navigation preview to obtain a binarized image; detecting the binarized image by using a contour detection function and separating a sample; carrying out boundary removal processing on the contour in the sample; and drawing the binarized image after the boundary removal processing into a final slice navigation preview. In the process of identifying the sample area by the digital slice scanner, the position of the cover glass needs to be identified, and the boundary is removed, so that the accuracy of identifying the sample area is improved.
Description
technical field [0001] The invention relates to a method and a device for removing the boundary of a cover glass in a digital slice scanner, belonging to the technical field of scanner image processing. Background technique [0002] Digital slice scanner is a device that combines digital image technology, mechanical control and micro-optical technology to digitize physical slices. Digital image technology is responsible for collecting and identifying images of sample areas; collecting microscopic and optically magnified images, and registering and splicing images to form high-resolution full-information images. The mechanical control completes the movement of the platform, and the sample area is gradually enlarged by the micro-optical technology through the movement. Micro-optic techniques are primarily used to magnify the sample area. [0003] In digital slide scanners, slices are placed into the device to form a navigation preview. The navigation preview image correspon...
