Prompt Title: Soft Edge Detection.

Soft edge detection is a video compression technique that is used to reduce the number of bits required to represent an image or video. The idea behind soft edge detection is to identify and remove the high-frequency components that exist at the edges of an image or video frame.

In traditional edge detection, sharp transitions between areas of high and low intensity are detected and emphasized, resulting in harsh edges. Soft edge detection, on the other hand, detects gradual transitions between different regions of an image or video and preserves them. This results in smoother edges that are less likely to cause artifacts or distortion in the compressed video.

Soft edge detection is typically used in conjunction with other compression techniques such as discrete cosine transform (DCT) or wavelet transforms. By identifying and removing high-frequency components at the edges of an image or video frame, soft edge detection can reduce the amount of data that needs to be stored or transmitted without sacrificing image quality.
