A method of processing an image signal comprising image and depth information is provided. The method is configured to perform segmentation on an image based on depth/disparity information present in the image signal comprising said image, and subsequently inpaint background for correction of the errors in the image around the foreground objects into a region that extends beyond the segment boundary of the foreground object and/or inpaint foreground for correction of errors in the image into a region that extends inside the segment boundary of the foreground object. In this way compression and other artifacts may be reduced.

Use of inpainting techniques for image correction

A method of image analysis, includes: obtaining a sequence () of images, each represented by pixel data; performing a vision-based analysis on at least one of the sequence () of images to obtain data for classifying a state of a subject represented in the images;&#x2014;determining at least one value of a physiological parameter of a living being represented in at least some of the sequence () of images; and classifying a state of the subject using the data obtained with the vision-based analysis and the at least one value of the physiological parameter. The at least one value of the physiological parameter is determined through analysis of image data from the same sequence () of images from which the at least one image on which the vision-based analysis is performed is taken. A method of enabling remote photoplethysmographic analysis includes: obtaining a sequence () of images from at least one camera (), each represented by pixel data representative of reflected ambient light in at least a limited range of wavelengths; and, for at least one measurement zone (), providing a signal representative of at least variations in a time-varying value of a combination of pixel values at least a number of image points in the measurement zone () for use in determining at least one value of a physiological parameter. At least part of a selected subject represented in the sequence () of images is tracked, and a directable light source () illuminating at least part of the selected subject is controlled.

Method and system for image analysis

A system and method for motion estimation involves obtaining input image frames, where the input image frames correspond to different instances in time, and performing motion estimation on the input image frames using depth information from the input image frames, where the depth information from an input image frame indicates how far a pixel in the input image frame is located from a surface of a three dimensional space.
