VIDEO PROCESSING APPARATUS, VIDEO PROCESSING METHOD AND PROGRAM - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240119600 titled 'VIDEO PROCESSING APPARATUS, VIDEO PROCESSING METHOD AND PROGRAM

Simplified Explanation

The patent application describes a video processing device that can accurately determine whether a pixel in an image is part of the foreground or background, and correct any errors in this determination caused by color changes.

• Foreground region estimation unit determines if a pixel is foreground or background.
• Blinking correction unit corrects errors in foreground/background determination caused by color changes.
• Uses a lookup table to determine if a color change is in the foreground or background.
• Corrects errors in determination caused by color changes in the foreground or background.

Potential Applications

This technology could be used in video editing software to accurately separate foreground objects from the background, allowing for more precise editing and special effects.

Problems Solved

This technology solves the problem of inaccurate foreground/background segmentation in video processing, which can lead to errors in editing and visual effects.

Benefits

The benefits of this technology include improved accuracy in determining foreground and background elements in videos, leading to better quality editing and visual effects.

Potential Commercial Applications

Commercial applications for this technology could include video editing software, security systems for object detection, and augmented reality applications.

Possible Prior Art

One possible prior art for this technology could be existing video processing algorithms that attempt to separate foreground and background elements in videos. However, the specific method of using a lookup table to correct errors caused by color changes may be a novel aspect of this patent application.

=== What are the specific technical details of the lookup table used in the blinking correction unit? The specific technical details of the lookup table, such as its size, structure, and how it is trained or generated, are not provided in the abstract.

=== How does the foreground region estimation unit differentiate between foreground and background pixels? The abstract does not detail the specific algorithm or method used by the foreground region estimation unit to determine whether a pixel is part of the foreground or background.

Original Abstract Submitted

a video processing device includes a foreground region estimation unit that determines whether a pixel of an input image is a foreground or a background, and a blinking correction unit that determines, for a target pixel on which a foreground and a background have been switched, whether switching between the foreground and the background is a color change in the foreground or in the background by using a lookup table capable of determining whether switching is in the foreground or in the background from a temporal change of a pixel value, and corrects a result of determination as to whether it is the foreground or the background that has been performed for the target pixel in a case where the switching between the foreground and the background is the color change in the foreground or in the background.
