Preprocessing Video/Image Data Based on Orange Pi AIpro

Preprocessing Video/Image Data Based on Orange Pi AIpro

01 Background Introduction Due to factors such as network structure and training methods, most neural network models have format restrictions on input data. In the field of computer vision, these restrictions are mostly reflected in image size, color space, normalization parameters, etc. If the source image or video does not meet the requirements of the … Read more

How to Convert Open Source Framework Models to Ascend Models Based on Orange Pi AIpro

How to Convert Open Source Framework Models to Ascend Models Based on Orange Pi AIpro

In the previous introduction, we discussed how to develop AI inference applications based on Orange Pi AIpro, and learned that before inference, the original network model (which could be PyTorch/TensorFlow/Caffe, etc.) needs to be converted into an .om model. Only then can we call the Ascend aclmdlExecute and other model execution interfaces for model inference … Read more
