Abstract

The invention provides a screening method and device for a blind area detection training set, a server and a storage medium. The method comprises the steps: inputting an image into a semantic segmentation neural network; acquiring an output matrix of a feature recognition deconvolution layer in the semantic segmentation neural network, wherein the output matrix is used for representing feature intensity corresponding to each pixel of the output image; mapping the output matrix to a basic image template to form a feature image, wherein the basic image template is used for highlighting the intensity of feature intensity; and calculating an image feature value mean value of a preset region of interest in the feature image, comparing the feature value mean value with a preset mean value threshold value, and when the feature value mean value is not greater than the preset mean value threshold value, determining that the image is added into a blind area detection training set. A unified, objective and visual prediction result of a data set can be obtained, and targets with poor feature extraction and uncertainty can be added to next training.
