Proposed approach Fig. 1: Overview of Proposed System Pre-Processing and Noise Correction The input image contains various noises or other time-scale rapid/structured phenomenon. These images need to have relatively slow changes of value by giving little attention to the close matching of data values which can be done by filtering/smoothing operation. SMPTE-C Color Space segmentation. SMPTE-C is the current color standard for broadcasting in America, the old NTSC standard for primaries. The white point is D65, the gamma correction value is 2.2 (Standard), and the chromaticities for SMPTE-C color space are: R: Xr = 0.630 Yr=0.340 G: Xg = 0.310 Yg=0.595 B: Xb = 0.155 Yb=0.070 White: Xn = 0.312713 Yn = 0.329016 Fig2: Flow of…show more content…
The tail light is not fully symmetric but having some symmetric criteria between single vehicle candidate tail lights such as Size, Shape etc. The size and shape of tail light which belongs to same vehicle is almost similar with 0-10 percent variation with each other. The reflection posses by same vehicle tail light are also equal. In similar way texture and color information is also helps to identify the one vehicle tail light. Beside these symmetry criteria the orientation of tail light is also important to select the pair lights. The tail lights is always in uniform orientation and the line joining the center of two tail light is always made an angle less than 5 degree from horizon. In turning and bending roads the angle doesn’t change much. The paired tail light must satisfy the condition Which shows that the tail lights belonging to same vehicle is maintain a distance and according to vehicle type it varies. On survey of distance between two tail lights and height of tail light ratio belonging to same vehicle, it found that it always more than 3 and less than 7. The pairing is done via two separate procedures as in a single detected object and separate object pair. These because of different color vehicle, the white and red vehicle are identified as single object in tail light segmentation. According to size (size > threshold) of detected object the searching of pair tail light done inside the detected object via above described properties. If
