Feature detection method and device, equipment, storage medium and computer program product

The embodiment of the invention provides a feature detection method and device, equipment, a storage medium and a computer program product, and the method comprises the steps: determining a feature detection operator for detecting image features according to the target size of a to-be-extracted feature in a target image, the feature detection operator has the following features: the feature detection operator after being rotated by 180 degrees is symmetrical to the feature detection operator before being rotated, and the element of each position in the feature detection operator after being rotated by 90 degrees is a negative number of the element of each corresponding position in the feature detection operator before being rotated; according to the feature detection operator, performing convolution processing on the target image to obtain an enhanced feature map; and determining a feature detection result according to the enhanced feature map. According to the embodiment of the invention, the accuracy of fea
