2014-02-26 14:02:10 -0600 | asked a question | Super-resolution of license plate in video sequence This is a follow up question to my question here: http://stackoverflow.com/questions/21715908/local-enhancing-of-license-plate-in-video-sequence I implemented a basic super-resolution technique suggested by the answer, but I am having trouble obtaining better resolution results. I trimmed the video sequence to 40 frames as seen below: and using the code below, which takes the first 5 frames and performs Super-resolution, then the super-resolved frame is repeatedly updated with the processing of the rest of the frames in the sequence: where the program calls and I obtained this resulting image:
As you can see there are only small improvements in the overall resolution, and not much improvement to the readability of the license plate. I've tried experimenting with the various parameters, but the parameters used above seem to be the best I can do. I am open to any suggestions for improvement (need not be limited to the use of C#/Emgu CV as above), and even different approaches in implementation. |

2014-02-12 17:39:35 -0600 | asked a question | Local enhancing of license plate in video sequence My goal is to create an enhanced image with a more readable license plate number from a given sequence of images with indistinguishable license plates on driving cars, such as the sequence below. As you can see, the plate number is, for the most part, indistinguishable. I am looking into implementations for enhancing such as super-resolution of multiple frames (as I have researched in this paper: http://users.soe.ucsc.edu/~milanfar/publications/journal/SRfinal.pdf). I have some experience with OpenCV, and I am looking for help in what direction to take, or if super-resolution is really the best option for this kind of problem. |
