Method and system of reconstructing videos by using super-resolution algorithm

A system of reconstructing videos by using super-resolution algorithm, the system comprising:

• a video providing module, used for providing a video, wherein the video is composed of a plurality of frames having a sequence;
• a thread starting module, used for starting a first thread and a second thread, the first thread performing a first algorithm and the second thread performing a second algorithm for improving resolution, wherein a time complexity of the first algorithm is greater than a time complexity of the second algorithm;
• the first thread, used for sequentially reading the frames of the video in units of a first interval and processing the frames in order to obtain first processed frames;
• the second thread, used for sequentially reading the frames of the video in units of a second interval and processing the frames in order to obtain second processed frames, wherein a value of the first interval is an integer greater than 1, and a value of the second interval is 1;
• a fusion operation module, used for performing a fusion operation on the second processed frames which is processed by the second thread and the nearest first processed frames which is processed by the first thread in order to obtain a plurality of fusion frames;
• and
• a displaying module, used for displaying the plurality of fusion frames according to the sequence;
• wherein the fusion operation module adopts the following formula for obtaining the fusion frames:
• F2F=A·F1H+B·F2L;
• wherein F2L represents the second processed frames which is processed by the second thread, F1H represent the first processed frames which is processed by the first thread and nearest to the second processed frames F2L, A, B∈Rm×n, and A and B meet the following relationship:
• {
