Embodiment Construction

[0070] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0071] In practical application, the inventor found that: since the existing data enhancement is mainly based on some basic transformations of the entire image, there may be a loss of foreground information, and since there is no change to the fixed scene or the change to the background complexity is limited, Therefore, it is easy to overfit ...

Abstract

The invention relates to a sample generation method and device, electronic equipment and a computer readable storage medium. The method comprises the steps of obtaining an initial sample image containing a pig body and a plurality of background images; extracting a pig body mask image from the initial sample image; performing foreground enhancement on the pig body mask image to obtain a pluralityof enhanced pig body mask images; and finally, performing fusion processing on each enhanced pig body mask image and the plurality of background images to obtain a plurality of training sample imagesand annotation information. According to the embodiment of the invention, loss of foreground information can be reduced; the over-fitting problem is avoided, manual annotation is not needed, and the labor cost is saved.

Description

technical field [0001] The present invention relates to the field of computers, in particular to a sample generation method, device, electronic equipment and computer-readable storage medium. Background technique [0002] At present, the market demand for pork is the largest among all animal meats. However, with the large-scale development of the pig industry, the number of pig detections has been far higher than the labor cost, and the real-time situation of pigs can be discovered in time through the detection of pigs. At present, the method of pig body detection has begun to use related algorithms of deep learning, but the demand for training data is large, and manual classification labeling is difficult to achieve. [0003] In order to expand the limited training data set, the existing data enhancement methods in deep learning can generate new training data by randomly adding jitter and disturbance to the original data, that is to say, do a certain amount of blurring to ...
