implementation of "Matching local self-similarities across images and videos"

This is the implementation of "Matching local self-similarities across images and videos"

Introduction

1 main：The main function includes reading the image, calculating the self-similarity descriptor of each picture, calculating the saliency score, and drawing the detection result;

2 com_Self_Similarities：Calculate the self-similarity descriptor;

2.1  cal_ssd：Calculate the SSD between patch and region；

2.2  get_self_sim_vec：Convert the similarity calculated in 2.1 to a self-similarity descriptor vector;

2.3  cart2polar： Convert Cartesian coordinates to a polar coordinate system; 

2.4  get_bin：Divide the polar coordinate system into 15*3=45 bins;

3 draw_result：Show results.
