## Application Scenarios

* **Massive image optimization**: It can be used to improve the quality of website pictures, mobile album pictures and video cover pictures, intelligently adjust the contrast of pictures, and solve the problem of too dark or too bright pictures.
* **Video Surveillance**: In security surveillance/vehicle system scenarios, video/images captured by light and extreme weather are optimized to reconstruct more discernible surveillance material.
* **Color printing photo beautification**: It helps color printing studios optimize the processing of photos before color printing, intelligently adjust the contrast of pictures, solve the problem of too dark or too bright pictures, and reduce the workload of designers. It can also be used to develop photo developing apps, small programs, etc.
