Abstract: A real-time object tracking method and an apparatus thereof using a color histogram capable of continuously tracing the change of an object which is chosen on a track station are provided to modify a reference histogram based on the present histogram of the window which is chosen on the track station. A histogram generator(30) produces a plurality of windows from a successively inputted image. A similarity calculator(40) produces the similarity with the set standards histogram by each present histogram. A tracking target selector(60) extracts a standards histogram and the most high present histogram among the current histograms. The window corresponding to the extracted present histogram is selected as a tracking window. A modifier(70) modifies the standard histogram by reflecting the standard histogram.

The image input unit receives image signals from a camera(200), converts the received image signals into digital image signals, and divides and outputs sync signals from the image signals. The image storage unit stores image data corresponding to an effective image section by frame out of the digital image signals on the basis of the sync signals. The code generation unit reads the image data stored in the image storage unit to perform the outline searching of an interest decoding area, and generates the chain code in correspondence to location correlation between adjacent pixels forming the outline of the interest decoding area according to a searching result. The image storage unit includes a first buffer memory and a second buffer memory, and stores the image data corresponding to the effective image section alternately in the first buffer memory and the second buffer memory whenever a frame is changed. When the image data is stored in one of the first buffer memory and the second buffer memory, the code generation unit reads image data from the other of the first buffer memory and the second buffer memory to generate the chain code.

Abstract: A real-time object tracking apparatus is provided to track a moving object using a particle filter in real time without a delay time. A real-time object tracking apparatus includes a memory, a subtracter, a filter, and a particle filter. The memory sequentially stores images of a moving object. The subtracter subtracts a previous frame from a current frame stored in the memory to obtain a subtracted image. The filter removes noise of the subtracted image. The particle filter tracks the moving object using the subtracted image from which the noise is removed. The particle filter distributes particles in the subtracted image and sets the moving direction of the moving object through the distribution density of the particles according to a probability approach in response to a variation in the particle state and a weight given to the particles.
