Abstract
The present invention provides an improved method and device for visual enhancement of a digital image in video applications. In particular, the invention is concerned with a multi-modal scene analysis for face or people finding followed by the visual emphasis of one or more participants on the visual screen, or the visual emphasis of the person speaking among a group of participants to achieve an improved perceived quality and situational awareness during a video conference call. Said analysis is performed by means of a segmenting module (22) allowing to define at least a region of interest (ROI) and a region of no interest (RONI).
Claims20
A method for processing video images, comprising:
- detecting at least one person in an image of a video application;
- estimating a motion associated with the at least one detected person in the image;
- segmenting the image into at least one region of interest and at least one region of no interest, wherein the at least one region of interest comprises the at least one detected person in the image;
- and
- applying a temporal frame processing to a video signal including the image by using a higher frame rate in the at least one region of interest than that applied in the at least one region of no interest.
A device for processing video images, comprising:
- a detecting module for detecting at least one person in an image of a video application;
- a motion estimation module for estimating a motion associated with the at least one detected person in the image;
- a segmenting module for segmenting the image into at least one region of interest and at least one region of no interest, wherein the at least one region of interest comprises the at least one detected person in the image;
- and
- at least one processing module for applying a temporal frame processing to a video signal including the image by using a higher frame rate in the at least one region of interest than that applied in the at least one region of no interest.
A computer-readable medium having executable instructions stored thereon which, when executed by a microprocessor cause the processor to:
- detect at least one person in an image of a video application;
- estimate a motion associated with the at least one detected person in the image;
- segment the image into at least one region of interest and at least one region of no interest,
- wherein the at least one region of interest comprises the at least one detected person in the image;
- and
- apply a temporal frame processing to a video signal including the image by using a higher frame rate in the at least one region of interest than that applied in the at least one region of no interest.
