Visual Tracking Using Max-Average Pooling and Weight-Selection Strategy
Algorithm 1
The proposed algorithm with max-average pooling.
Input: An image from the video sequences, the center point of the bounding box, the noise coefficient | , and the number of particles . | (1) Sample particles around the initial point of the bounding box, and the distribution of the particles | is the normal distribution, which is implemented by the function randn. | (2) Initialize the dictionary using tracking results of the first ten frames. | (3) Compute the formula to obtain the sparse codes: | Note that and , where is the size of the patch’ width by height. | (4) Pool the features by computing: | (5) Compute the error of reconstruction: | | (6) Finally, obtain the particle which is corresponding to the minimum error. |
