Struck tracking algorithm (4)

Next, we analyze raw features and histogram features.

Raw features: scales an image to a 16*16 pixel space. The pixel values are dimmed to (0, 1). Combined with the Gaussian Kernel function, then we get the 16*16 = 256 feature vector.

Histogram features: The image is divided into four layers, and the I layer is divided into I * I cells. Each cell calculates its 16 intensity histogram Statistical Distribution vectors, the feature dimension is (1 + 4 + 9 + 16) x 16 = 480 dimension.
