Abstract
The invention relates to a seriously degraded license plate image information recovery method. According to the method, a convolutional neural network is used to learn priori knowledge required by seriously degraded license plate information extraction; training and fine adjustment of the convolutional neural network are carried out by adopting the simulated license plate image and the real license plate image, and the character output probability of each license plate character position is obtained by adopting a SoftMax output form, so that a decision basis is provided for license plate information extraction, and unified processing of character segmentation and recognition is achieved. According to the method and the process, extraction of seriously degraded license plate information iseffectively realized, and extraction of all low-resolution license plate information is facilitated. The method can help the public security department to obtain meaningful evidences and clues, and has the maximum application value.
