Patent Images

1. A method for processing an image, comprising:

  • in response to receiving an image processing request for a target image sent by a client, acquiring an original image containing the target image and other sub-images;

    extracting frequency domain features of the original image, and generating a spectrogram of the original image based on the extracted frequency domain features;

    determining the intensity degree of gray scale change of a target image, determining a frequency domain feature for filtering aiming at the target image from a preset frequency domain feature library for filtering according to the determined intensity degree, filtering the generated spectrogram by using the frequency domain feature for filtering to remove frequency domain features which do not belong to the target image, and generating a filtered spectrogram;

    converting the frequency spectrogram after the filtering processing into a time domain graph, and performing saliency processing on the time domain graph to enhance the image characteristics of the target image to generate a saliency map, wherein the saliency processing is used for extracting the saliency characteristics of the time domain graph;

    and adjusting the gray value of each pixel point included in the saliency map based on a preset gray threshold value to generate an adjusted saliency map.
