Abstract: Text region detection techniques and systems for digital images using image tag filtering are described. These techniques and systems support numerous advantages over conventional techniques through use of image tags to filter text region candidates. A computing device, for instance, may first generate text region candidates through use of a variety of different techniques, such as text line detection. The computing device then assigns image tags to the text region candidates. The assigned image tags are then used by the computing device to filter the text region candidates based on whether image tags assigned to respective candidates are indicative of text.

Abstract: In processing and compressing three-dimensional video data, a first color macroblock (MB) and a first depth MB is acquired from a frame. The first depth MB is down-sampled to obtain a second depth MB. Depth information of the second depth MB is embedded to the first color MB, to create a second color MB. The second color MB is compressed and entropy encoded, to obtain video encoding data. The video encoding data is entropy decoded and decompressed, to obtain a third color MB. Depth information, brightness information, and chroma information are acquired from the third color MB, to create a third depth MB and a fourth color MB. A fifth color MB is created according to up-sampled third depth MB and the fourth color MB. The fourth color MB and the fifth color MB are synthesized into the three-dimensional video data.

Abstract: An audio processing method for an electronic device includes a first audio file, a second audio file, and a first digital watermark to perform an audio processing method. The first digital watermark has ownership information regarding the first audio file. A first discrete audio array of the first audio file and a second discrete audio array of the second audio file are generated. A cipher code is generated using the first discrete audio array and the first digital watermark, and a second digital watermark is generated using the cipher code and the second discrete audio array. The first and second digital watermarks are compared, to confirm common ownership or otherwise of the second and first audio files.

Abstract: Techniques for detecting and recognizing text may be provided. For example, an image may be analyzed to detect and recognize text therein. The analysis may involve detecting text components in the image. For example, multiple color spaces and multiple-stage filtering may be applied to detect the text components. Further, the analysis may involve extracting text lines based on the text components. For example, global information about the text components can be analyzed to generate best-fitting text lines. The analysis may also involve pruning and splitting the text lines to generate bounding boxes around groups of text components. Text recognition may be applied to the bounding boxes to recognize text therein.

Abstract: A computer-implemented method of playing a game includes displaying a first plurality of game elements on the display device, receiving a selection from the user, wherein the selection comprises a first game element of the plurality of game elements and at least one second game element of the plurality of game elements, and wherein an appearance of the first game element matches an appearance of the at least one second game element, displaying the selection as an enclosed area that encompasses the first game element and the at least one second game element, determining a second plurality of game elements, wherein each of the second plurality of game elements have an appearance that matches the appearance of the first game element and are located within the selection, and calculating a target score wherein the target score is based on a number of the second plurality of game elements.

Abstract: An electronic device for converting a multi-channel audio file to a dual channel audio file and vice versa. The multichannel audio file includes a right channel group and a left channel group of channel signals. The electronic device respectively mixes the channel signals of the right channel group and the left channel group according to a mixed matrix to form N mixed signals, and cross embeds the N mixed signals to from a left channel audio signal and a right channel audio signal to compose the dual channel audio file. The electronic device samples, recombines and decodes the left channel audio signal and the right channel audio signal according to a decoding matrix, which is the inverse of the mixed matrix, to revert to the original multi-channel audio file.
