• API function: Calculates the transparency multiplication of tensors RGB, frame, and alpha.

• Formulas:

$$out_{i*3}=rgb_{i*3} * (alpha_i / 255) + frame_{i*3}*(1 - alpha_i/255)$$ [object Object]

Each operator has calls. First, aclnnBlendImagesCustomGetWorkspaceSize is called to obtain the workspace size required for computation and the executor that contains the operator computation process. Then, aclnnBlendImagesCustom is called to perform computation.
