Abstract

The present invention provides a 3D filtering method based on monitoring scenes. The method includes: dividing the target frame image into a plurality of non-overlapping pixel blocks; determining the type of the target block in turn, and the type includes static blocks and moving blocks; If the target block is a moving block, adjust the movement intensity of the target block and the multi-layer surrounding blocks distributed around the target block from inside to outside, from large to small; control all Each pixel point in the target block and the surrounding blocks is filtered with the adjusted target motion intensity. The invention adjusts the motion intensity of the moving block and the multi-layer surrounding blocks around the moving block in a layer-by-layer decreasing manner from the inside to the outside, which is beneficial to the uniform transition of the motion intensity of the pixel blocks in each layer and avoids the difference in the motion intensity of the moving block and the static block. Larger resulting in obvious block effect.

Description

technical field [0001] The invention relates to the field of image filtering, in particular to a monitoring scene-based 3D filtering method. Background technique [0002] At present, with the rapid development of the field of security monitoring, users have gradually increased their requirements for the clarity of surveillance video images. However, during the process of digitalization and transmission, video images are often disturbed by noise from imaging equipment and the external environment, and noise images with small and rough spots are prone to appear, reducing the clarity of video images. Therefore, it is necessary to adopt an appropriate noise reduction method to reduce the impact of noise on video images. [0003] 3D (three-dimensional, English full name: three dimensional) filtering method is a commonly used video image noise reduction method. The 3D filtering method uses reference frame images (such as adjacent historical frame images) as the filtering referen...
