Change Description

The Kunpeng Computer Vision Library (KPCV) contains optimizations of the OpenCV image operators and PyTorch image operators, and uses Kunpeng vector instructions to optimize the image processing operators. Table 1 lists the operators in KPCV.

Description

1

CV image operator library

Kunpeng vector instructions are used to optimize image processing operators in this library, including merge, resize (it supports multiple interpolation modes, such as cv2.INTER_LINEAR, cv2.INTER_CUBIC, and cv2.INTER_NEAREST_EXACT), remap, dilate, GaussianBlur, and cvtColor.

2

PyTorch image operator library

Kunpeng vector instructions are used to optimize data preprocessing operators in this library, including normalize, resize, and permute.
