[0060] The principles and features of the present invention will be described below with reference to the accompanying drawings. The examples cited are only used to explain the present invention, and are not used to limit the scope of the present invention.
[0061] Such as figure 1 As shown, the filter bank training method of the present invention specifically includes the following steps:
[0062] Step 1: The preprocessing module preprocesses the training images marked with target locations to obtain a denoising training image set that reduces the effects of lighting and shadows;
[0063] Step 2: The clustering module performs initial clustering on the denoising training image set, so that the denoising training image set is decomposed into K training sets according to appearance;
[0064] Step 3: The ideal filter design module designs an ideal filter output model based on the target position label in the training image described in step 1, and the target position in the ideal filte...
