[0062] Such as figure 1 As shown, a method for estimating crowd density based on a content-aware module provided by the present invention includes:
[0063] S1. Preprocessing the image data to be predicted;
[0064] in,
[0065]Preprocessing is to be able to input the convolutional neural network model for prediction, and the image needs to be preprocessed; the width and height of the input image must be limited to 512×512. In order to ensure that the image will not be deformed, do not choose the way of directly resizing to 512×512 , but choose the method of padding and random cropping. Images smaller than this size will be filled with black pixels in the lower right corner to complete the size to 512×512. Images larger than this size will be randomly cropped first, and the undersized part will be trimmed after cropping. Fill of black pixels.
[0066] S2. Input the processed data into the convolutional neural network model;
[0067] in,
[0068] Such as image 3 , 5 As ...
