CPC Class H04N

The technology described in this document can be embodied in a method that includes receiving from a sensor, information indicative of an environmental condition. The method also includes receiving first information indicative of whether or not a first image captured by a first image acquisition device corresponds to an alternative representation of a live person, and receiving second information indicative of whether or not a second image captured by a second image acquisition device corresponds to the alternative representation. The first information and the second information are combined in a weighted combination, the corresponding weights being assigned in accordance with the environmental condition. A determination is made, based on the weighted combination, that a subject in the first and second images is an alternative representation of a live person, and in response, access to the secure system is prevented.

A non-transitory computer-readable recording medium recording a character area extraction program for causing a computer to execute a process includes changing a relationship in relative sizes between an image and a scanning window that scans the image; scanning the scanning window based on a changed relationship, specifying a scanning position at which an edge density of an image area included in the scanning window is equal to or larger than a threshold value, extracting one or more areas indicated by the scanning window at the specified scanning position as one or more character area candidates, determining, when overlapped character area candidates included in the one or more character area candidates overlap with each other, a maximum character area candidate having a maximum edge density among the overlapped character area candidates, and extracting the image area included in the maximum character area candidate as a character area.

Motion compensation in a systems for transmission of images via channels of communication with a limited capacity by means of application of compression of the images. A technical result consists in an increase of the compression degree upon encoding such that a high degree of compression is provided without an increase in the computational power of the encoding device and without additional distortion upon decoding. The result is obtained in part by the usage of a more effective method of interpolation of restored subsamples, employing an adaptive and applicative set of samples, which are used to restore a quantized signal. Use of this set of samples facilitates an improvement in an accuracy of the interpolation.

The present disclosure includes systems, methods, and non-transitory computer readable media that efficiently and accurately identify matching designs and sub-shapes across one or more digital canvases in order to provide one or more development tools for rapid and efficient editing of the digital canvases. In particular, one or more embodiments utilize a transformation-agnostic method of identifying matching designs and sub-shapes between multiple digital canvases. Furthermore, in response to identifying a set of matching designs or sub-shapes, one or more embodiments generate a mapping between the matching designs or sub-shapes. Utilizing this mapping, one or more embodiments provide various tools that enable rapid and efficient development of robust digital canvases, while minimizing system storage burdens.
