Computer-implemented method of enhancing object detection in a digital image of known underlying structure, and corresponding module, data processing apparatus and computer program

Abstract

A computer-implemented method of enhancing object detection in a digital image of known underlying structure using pre-processed images with underlying structure and with any objects detected and bounding boxes inserted over the objects, the method comprising: extracting or generating images with the underlying structure but without objects detected as negative images; extracting images with the underlying structure and with an object detected as positive images; inputting pairs of negative and positive images through a feature extraction section in a neural network to extract feature vectors of the images; contrasting feature vectors of each pair of positive and negative images and thereby provide a contrast vector and gating the result to form an attention vector; processing the attention vector and the feature vector of the positive image to produce an output.
