Disclosed are an apparatus, a method, and a system for identifying a laser spot and locating coordinates of the laser spot. The apparatus comprises a foreground calculation unit used to calculate a foreground image in an input image captured by a camera device; a threshold value estimation unit used to automatically estimate, at an initialization stage, pixel brightness threshold values, pixel degree-of-saturation threshold values, and a pixel color-tone threshold value range based on the foreground image; a laser spot detection unit used to detect, at a processing stage, the laser spot based on the foreground image as well as the pixel brightness threshold values, the pixel degree-of-saturation threshold values, and the pixel color-tone threshold value range; and a coordinate locating unit used to calculate the coordinates of the laser spot in the input image based on the laser spot detected by the laser spot detection unit.

Disclosed are a white balance device and a white balance method. The device comprises a unit used to extract background pixels of an image; a unit used to obtain representative color of background; a unit for determining a global magnification ratio of the background pixels; a unit used to carry out pre-adjustment with regard to original color of each of the background pixels; a unit used to, for each of the background pixels, determine expected final background color of the corresponding background pixel, and then determine an accurate magnification ratio of the corresponding background pixel; and a unit used to, for each of the background pixels, carry out adjustment with regard to the original color of the corresponding background pixel by using the accurate magnification ratio of the corresponding background pixel.

The present disclosure introduces a method, an apparatus, and a system of processing repetitive data. In an example embodiment, the data structure of the comparison data to be compared is processed as having a same data structure of the data in the repetition database. The repetition database is formed by an internal memory mapping after processing data in a database according to a preset data structure. The processed comparison data is compared with data in the repetition database to determine whether the comparison data is repetitive data. After it is determined that the comparison data is not repetitive data, the comparison data is written into the database. The techniques described herein improve the efficiency of the servers for eliminating repetitive data and save the server resources.

Disclosed are a virtual touch panel system and an interactive mode auto-switching method. The virtual touch panel system comprises a projector configured to project an image on a projection surface; a depth map camera configured to obtain depth information of an environment containing a touch operation area; a depth map processing unit configured to generate an initial depth map, and to determine the touch operation area based on the initial depth map; an object detecting unit configured to detect, from each of plural images continuously obtained by the depth map camera after the initial circumstance, a candidate blob of at least one object located within a predetermined distance from the determined touch operation area; and a tracking unit configured to insert each of the blobs into a corresponding point sequence according to a relationship of the geometric centers of the blobs detected in adjacent two of the obtained images.

Systems and methods for smooth rewind playback of streamed media are provided. The media includes relatively-encoded frames and independently-encoded frames. The method includes receiving a rewind request indicating a rewind speed for rewind playback of the media, selectively dropping relatively-encoded frame(s) based on a receipt constraint and a decoding constraint to form a subset of the media, and receiving frames of the subset. The method further includes selecting, in a reverse order, a selected group of pictures (GOP) included within the subset, and decoding relatively-encoded frame(s) of the GOP in a forward sequential frame order. The method further includes caching relatively-encoded frame(s) of the GOP in the forward sequential frame order, and when caching, dropping and overwriting relatively-encoded frame(s) of the GOP selectively according to a memory constraint and/or a display constraint. The method further includes displaying relatively-encoded frame(s) of the GOP in a reverse sequential frame order.

Described is a technology by which code, such as an untrusted web application hosted in a browser, provides content through an interface for playback by an application environment, such as an application environment running in a browser plug-in. Content may be in the form of elementary video, audio and/or script streams. The content is in a container that is unpackaged by the application code, whereby the content may be packaged in any format that the application understands, and/or or come from any source from which the application can download the container. An application environment component such as a platform-level media element receives information from an application that informs the application environment that the application is to provide media stream data for playback. The application environment requests media stream data (e.g., samples) from the application, receives them as processed by the application, and provides the requested media stream data for playback.
