Abstract: The disclosure is related to a method and a system for processing composited images. The method is operated in a computer. A software-enabled user interface is provided for a user to create a composited image using a touch screen. In the beginning, in response to the user's manipulation, at least two images are retrieved from a database. A background image and a foreground image are selected from the images. The user interface allows the user using a gesture over the background image displayed on the touch screen for generating a series of touch signals covering a specific area. The touch signals render a mask image. The mask is applied to the foreground image. The mask image of the background image covers the foreground image so as to create a new foreground image. The composited image is created when the new foreground image is composited with the background image.

Abstract: A display device includes a main signal processing circuit to which color video data is input, and a plurality of sub-signal processing circuits to which video data for respective colors output by the main signal processing circuit are input. The main signal processing circuit generates information, which is used when each of the sub-signal processing circuits performs a predetermined process, based on information of a plurality of colors in the color video data input, and then outputs data representing the generated information to each of the sub-signal processing circuits together with the video data for the respective colors.

Abstract: Perceived strength of signals conveying images or sound to the brain can be increased based on persistence of vision or persistence of hearing. For example, when the eye or ear perceives a signal it takes a finite time to process it and send it to the brain. During that time the eye or ear does not recognize input and is, in effect, “turned off”. These periods of “unused” input are utilized to increase the intensity of the signal that the brain perceives. An exemplary system includes a switch, configured to route a signal alternatively to two paths—one of which includes a delay circuit that delays that signal by an amount equal to the persistence of vision or persistence of hearing interval. The exemplary system also includes a combiner that combines output from the two paths, so as to provide the brain with a signal that it will perceive as being twice as intense as the original.

The first signal and the second signal are mixed based on color information of the pixel of interest. Jaggies are effectively ameliorated by replacing the value of the pixel of interest with the mixing result.

At the outset, the switcher identifies active elements within the video effect, the comprising those elements that undergo a change during execution of the video effect, as opposed to those that remain inert during effect execution.

The offset value is applied to each subsequent interpolation of the video effect, thereby creating the desired result of applying only relative changes to the active elements of the video effect.

Abstract: A new framework for video compressed sensing models the evolution of the image frames of a video sequence as a linear dynamical system (LDS). This reduces the video recovery problem to first estimating the model parameters of the LDS from compressive measurements, from which the image frames are then reconstructed. We exploit the low-dimensional dynamic parameters (state sequence) and high-dimensional static parameters (observation matrix) of the LDS to devise a novel compressive measurement strategy that measures only the dynamic part of the scene at each instant and accumulates measurements over time to estimate the static parameters. This enables us to lower the compressive measurement rate considerably yet obtain video recovery at a high frame rate that is in fact inversely proportional to the length of the video sequence. This property makes our framework well-suited for high-speed video capture and other applications.
