Reducing the Impact of Stroboscopic Effect on the Results of Vehicles’ Plate Recognition Using Super-Resolution Techniques by Non-Coherent Camera Triggering
register license plate number recognition, super-resolution, camera triggering
The use of super-resolution algorithms can increase the resolution of image subject to further analysis in relation to the physical resolution of the camera recording the video sequence. A typical recording of such sequence is done with a fixed time interval (pre-determined number of frames per second). This can cause the shift of the plate image for subsequent frames by the total number of pixels, resulting in inability to take advantage of super-resolution algorithms that require shifts or rotations by a fractional part of pixels both vertically and horizontally. A possibility of reducing the impact of this effect by non-coherent triggering cameras is suggested in the paper.
