Embodiment Construction

[0037]The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. It should be noted that like numerals and letters denote similar items in the following figures, therefore, once an item is defined in one figure, it does not require further definition and explanation in subsequent figures. The term "comprises", "comprises" or any other variation thereof is intended to cover a non-exclusive inclusion such that a process, method, article or apparatus comprising a set of elements includes not only those elements but also other elements not expressly listed elements, or also elements inherent in such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising a ..." does not exclude the presence of additional identical elements in the process, method, article or apparatus comprising said element. The terms "first",...

Abstract

The application relates to the technical field of deep learning, and provides a model construction method and device, an image processing method and device, a hardware platform and a storage medium. The model construction method comprises the steps that a neural network model used for image processing is trained, wherein the neural network model comprises at least one depth separable convolution module, and each depth separable convolution module comprises a layer-by-layer convolution layer, a point-by-point convolution layer, a batch normalization layer and an activation layer which are connected in sequence; and the trained neural network model is quantized to obtain a quantized neural network model. According to the method, firstly, model parameters are quantified, so that the data volume of the parameters is effectively reduced, and the model is suitable for being deployed in NPU equipment. Secondly, the depth separable convolution module in the method is different from the depth separable convolution module in the prior art, and a batch normalization layer and an activation layer are not arranged between a layer-by-layer convolution layer and a point-by-point convolution layer, so that values of model parameters are distributed in a reasonable range, and the model parameters can be quantized with high precision.

Description

technical field [0001] The present invention relates to the technical field of deep learning, in particular, to a model building and image processing method, device, hardware platform and storage medium. Background technique [0002] Image processing technology is widely used in many fields, including face recognition and intelligent video analysis in the security field, traffic scene recognition in the traffic field, content-based image retrieval and automatic album classification in the Internet field, image recognition in the medical field, etc. In recent years, the industry has generally adopted neural network models to perform image processing tasks in specific fields, and achieved good results. [0003] Since the neural network model involves a large number of calculations, in the prior art, a Graphics Processing Unit (GPU) is generally used to accelerate calculations. However, the GPU has a large volume and relatively high power consumption. Unable to install. At pr...
