METHOD, DEVICE, USER EQUIPMENT AND COMPUTER PROGRAM FOR OBJECT EXTRACTION FROM MULTIMEDIA CONTENT

摘要

A method and a device (100) for extracting objects of a multimedia content are disclosed. The multimedia content comprises multiple image segments and each image segment comprises multiple pixels. The device calculates (S1) a force reflecting an edge strength for at least two pixels in an image segment of the multiple image segments. The device (100) identifies (S2) at least two interest points among the pixels in the image segment based on the calculated forces for the at least two pixels. Each interest point is associated with a directionality and exit points. The directionality gives an angle indicative of a strength of the force. The exit points are used for connecting one interest point to another interest point. The device (100) creates (S3) at least one contour by connecting the at least two interest points by using at least one predefined pattern, selected from a number of predefined patterns. The device (100) extracts (S4) the at least one created contour. Furthermore, the device (100) extracts (S5) at least one object from the at least one extracted contour. A corresponding computer program is also disclosed.
