Abstract:
1. An object image transformation method, comprising: capturing consecutive frames of the object's image, the consecutive frames including a number of elements; determining a frame difference for each of said elements; and processing the captured image and outputting an image data, wherein the image processing includes a sum accumulation of the frame difference for each of said elements from no less than two consecutive image frames, wherein the accumulation of the sum of the frame difference for each element of consecutive frames is carried out according to the following formula: where R i ≧0- is the resulting signal of the i-th element of the processed image, which is taken equal to zero in case of obtaining a negative value in the formula; X X M - is the number of frames being processed in the frame sequence; L - is the rate coefficient of the process being revealed; N - is the averaging coefficient D - is the threshold value of the image noise level.
