example 1

[0239] Increase the diversity of input images through a large number of sample data enhancements to avoid network overfitting.

[0240] Training neural network, structure extraction features, including residual network and deep layer aggregation (deep layeraggregation, DLA). Feature upsampling using a U-Net-like network. The network outputs two channels, including: a channel that outputs a masked image of the nucleus, and another channel that outputs a masked image of the overlapping portion of the nucleus boundary.

[0241] The outputs of the two channels were post-processed using a random walk algorithm and a watershed algorithm to separate adjacent nuclei.

[0242] Through a random forest classifier, some false detections are eliminated and the accuracy rate is improved.

[0243] The implementation of increasing image diversity can be as follows:

[0244] Use random cutting, random rotation, random flip, color perturbation, brightness contrast perturbation, limited contr...

Abstract

The embodiment of the invention discloses a medical image processing method and a device, an electronic device and a storage medium. The medical image processing method comprises the following steps of: acquiring a first mask image of an object in the medical image; Acquiring a second mask image of an area where an adjacent boundary of the plurality of targets is located; Separating the object inthe medical image in combination with the first mask image and the second mask image.

Description

technical field [0001] The present invention relates to the field of information technology, in particular to a medical image processing method and device, electronic equipment and a storage medium. Background technique [0002] Medical imaging can be an image of the body part of the patient. Through the collected images, medical personnel can observe the features other than the surface layer of the patient's body, or zoom in and observe the microscopic features that cannot be seen by the naked eye, so as to make a diagnosis. [0003] In order to further facilitate the diagnosis of medical personnel, electronic equipment will be used to process the collected medical images, so as to obtain images that are more convenient for medical personnel to observe or provide diagnostic auxiliary information. However, in related technologies, the processing effect of the medical image is still not good, for example, the segmentation effect of the target in the medical image is inaccurat...
