5A to 5E are diagrams for explaining a vehicle number recognition process of the intermittent server which is a constitution of the present invention.

5A, a local binary pattern (LBP) is calculated as a value calculated for all pixels of the image, and the LBP Is an index value obtained by coding the relative brightness change of the surrounding 3x3 region in binary. In other words, if a pixel is brighter than the center pixel, it is encoded as 1, and when it is dark, binary values can be used as an index for the local texture.

As shown in FIG. 5B, the histogram is calculated for the index values calculated for the respective pixels, and then the histogram is divided into cells of a predetermined size based on the texture for the corresponding image region, and LBP A histogram for the histogram is obtained, and a vector obtained by connecting the histograms in a line is utilized as the final feature data, i.e., the first learning data.

In other words, large scale texture information can be extracted by using LBP in block units instead of pixels, and MB-LBP (Multi-scale Block-Local Binary Pattern) can be calculated for different scales and image positions. It is possible to extract various features for the object of

Through this process, we can extract a myriad of LBP features for one object. We can use AdaBoost learning algorithm to automatically select LBP features with high discrimination among them.
