Embodiment Construction

[0042] The nouns involved in the embodiments of the present application will be explained below:

[0043] The original image is any one of multiple frames of images obtained after decoding and decomposing the input video, and the multiple frames of images are continuous in time. It can be understood that the original image is an image before background segmentation and compression processing. The image format of the original image is the original image format.

[0044] The foreground image is obtained by segmenting the foreground area and the background area of ​​the original image by using the background modeling method, which retains the information related to object detection in the original image and removes the background information. For example, if the original image is a road traffic monitoring image, then the foreground image may include pedestrians, motor vehicles, non-motor vehicles, and the like.

[0045] The background image is obtained by segmenting the foregro...

Abstract

An embodiment of the present application provides an image processing method and device thereof, wherein the method includes the following steps: converting the foreground image corresponding to the original image into a compressed image; estimating the first extraction time required for depth feature extraction using the original image and the second extraction time required for depth feature extraction using the compressed image; according to the first extraction time and the second extraction time, it is determined to use the original image for depth feature extraction or use the compressed image for depth feature extraction. By adopting the embodiment of the present application, the calculation amount of the image depth feature extraction process can be effectively reduced, thereby improving the execution time of video object detection.

Description

technical field [0001] The embodiments of the present application relate to the technical field of image processing, and in particular to an image processing method and device thereof. Background technique [0002] Deep learning is a new field in machine learning research. Its motivation is to establish and simulate the neural network of human brain for analysis and learning. It imitates the mechanism of human brain to explain data, such as images, sounds and texts. With the rapid development of artificial intelligence technology represented by deep learning, deep learning technology has begun to be used in scenarios such as image classification and object detection in real environments. Object detection refers to determining the location of all objects contained in a given image and providing the category of each object. Video-based object detection and recognition technology has a wide range of application scenarios. For example, vehicle recognition in traffic surveillanc...
