Abstract

The invention provides a video data labeling method and device, an electronic device and a computer readable medium. The method comprises the following steps: acquiring video data to be labeled; and performing background removal processing on the video data to obtain post-processing video data; pre-labeling the post-processed video data by using a pre-training model to obtain pre-labeled data, sothat the pre-labeled data is manually adjusted to obtain labeled data of the video data. According to the scheme, the influence of the background in the video on labeling can be removed, labeling personnel do not need to start labeling from the beginning and only need to make a small amount of adjustment on the pre-labeled data, and compared with the prior art, the labeling efficiency of the videodata can be improved, and the labeling result is more accurate.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to a video data labeling method and device, an electronic device, and a computer-readable medium. Background technique [0002] With the rise of the machine learning boom, data-driven is one of the main means to improve the performance of the model, and the demand for practical applications is constantly being raised. However, the cost of data labeling itself is extremely high. There are two main reasons for this problem. On the one hand, data labeling requires a lot of manual correction and verification, and on the other hand, it is because of the labeling of data between different tasks of machine learning. Needs vary. [0003] Usually, people directly label the target objects in the picture manually, or first use a pre-trained model for preliminary labeling, and then provide them to labelers for manual labeling. However, for scenes with complex backgrounds or...
