Abstract: The continuous wavelet transform is widely used in image processing, especially in the area of object tracking. Currently the most popular wavelet used in object tracking is Gabor wavelet, Morlet wavelet and so on. This paper puts main attention on the theory and the implementation procedure of the object tracking process using two-dimensional spatio-temporal continuous wavelet, brings this wavelet transform to the tracking of small target and infrared target, and a good tracking result is obtained.

Key words: object tracking, Gabor wavelet, spatio-temporal wavelet, Morlet wavelet
