CSC Configuration
After confirming the image formats before and after AIPP (that is, the image format of the model input and image format during model training), you can determine the CSC parameter values. (The value of matrix_r*c* is fixed and does not need to be adjusted.) The following describes some configuration references.
Before AIPP, the following two typical CSC configurations are provided for the images or videos (in various color encoding modes such as YUV420SP_U8, XRGB8888_U8, RGB888_U8, and YUV400_U8) input to the model:
- For JPEG image files (such as JPG, JPEG, JPG, and JPEG), you can select from the CSC configurations in the JPEG columns in the following tables.
- For the decoded video data, the CSC parameters can be configured according to different color video digital standards (such as BT.601 and BT.709).
