Description

technical field

[0001] The invention belongs to the field of convolution network, in particular to an image processing method based on winograd dynamic convolution block. Background technique

[0002] Convolutional neural network (CNN) is a set of deep learning algorithms that perform well on a variety of AI tasks, including video surveillance, speech recognition, natural language processing, and autonomous driving. Over the past decade, CNNs have shown great promise and been the focus of a great deal of research. Convolutional layers are memory-intensive, computationally intensive, and prevalent in many advanced CNNs, including AlexNet, VGG, OverFeat, and ResNet. Therefore, the convolutional layer is the main factor affecting the overall performance of CNN.

[0003] Massive datasets and more complex models can provide satisfactory results and significantly improve the final accuracy of the task. However, it also results in increased training overhead and more computation...
