The invention discloses an image classification preprocessing method and device, an image classification method and device, equipment and a storage medium. The image classification preprocessing method comprises the following steps: determining a floating point transformation step length according to a target image resolution, a preset image sampling frequency and an initial image resolution; rounding the floating point transformation step length through a preset integer simulation method to obtain an upward integer transformation step length and a downward integer transformation step length; determining a first step length loss weight according to the upward integer transformation step length and the floating point transformation step length; determining a second step length loss weight according to the downward integer transformation step length and the floating point transformation step length; and according to the floating point transformation step length, the upward integer transformation step length, the downward integer transformation step length, the first step length loss weight and the second step length loss weight, adjusting the initial image resolution from the initial image resolution to the target image resolution to obtain an image to be classified. According to the invention, during image preprocessing, the feature integrity of the image is ensured, and the accuracy of image classification is improved.
Description
technical field [0001] The present invention relates to the technical field of image processing, in particular to an image classification preprocessing, an image classification method, a device, a device and a storage medium. Background technique [0002] With the development of science and technology, computer vision technology is a technology that uses machines to understand and analyze images, and computer vision technology is applied in image classification and other fields, replacing the manual method of image classification and improving the efficiency of image classification. [0003] When classifying images, there may be some images that only contain subtle features that are not easy to distinguish. In the prior art, when computer vision technology performs image classification processing, it is necessary to perform image preprocessing such as scaling, rotation, and cropping on the image. After the image is processed by the above image preprocessing method, the subtl...
