    Abstract: A channel information feedback method for multi-antenna system, and a wireless communication device using the same method are provided. The proposed method could reduce feedback overhead for multiple-input multiple-output (MIMO) wireless channel information, and is based on compressive sensing technique. Prior to sending back channel information, a receiver estimates the channel and multiplies the vectorized channel with a random matrix to generate compressed feedback content. Upon receiving the compressed feedback content at a transmitter, the channel information could be restored with signal recovery algorithms of compressive sensing technique. In the other embodiment, the proposed method further adaptively adjusts compression ratio of the compressed feedback content in accordance to the prevailing channel quality. Further, for slow-varying MIMO channels, there is proposed another channel information feedback method which switches between a fixed sparcifying-basis and a signal-dependent sparcifying-basis.

  • Patent number: 8842220
    Abstract: This invention enables, for example, reduction of motion blur in a hold-type display device and reduce flicker in an impulse-type display device by a simple process. For this purpose, an LPF filters a frame of input image data (A[i]) to generate low-frequency image data (L). A subtractor and an adder generate high-frequency image data (SH). Another adder adds the low-frequency image data (L) from a delay circuit to subsequent low-frequency image data. A divider halves the sum to generate low-frequency averaged image data (SL). A switch alternately outputs the high-frequency image data (SH) and the low-frequency image data (SL) every time a frame of image data is input. As a result, the apparatus of this invention can generate output image data having a frame rate twice that of the input image data.

    Abstract: A method for de-interlacing interlaced video includes receiving a first video field and a second video field, generating a first video frame by inserting the first video field in the first video frame on every second line of the first video frame, and by inserting a first synthesized video field on the lines of the first video frame not populated by the first video field. The video data of the first synthesized video field is based on video data of the first and second video fields. A second video frame is generated by inserting the second video field in the first video frame on every second line of the second video frame and by inserting a second synthesized video field on the lines of the second video frame not populated by the second video field. Two de-interlaced video frames are output for every received interlaced video frame.

  • Patent number: 8643777
    Abstract: A pixel interpolation process is based on detection of a potential edge in proximity to a pixel being estimated, and the angle thereof. The potential edge and its angle is determined based on filtering of offset or overlapping sets of lines from a pixel window centered around the pixel being estimated and then cross-correlating the filter results. The highest value in the correlation result values represents a potential edge in proximity to the pixel being estimated and the index of the highest value represents the angle of the potential edge. This information is used in conjunction with other information from the cross-correlation and analysis of the differences between pixels in proximity to verify the validity of the potential edge. If determined to be valid, a diagonal interpolation based on the edge and its angle is used to estimate the pixel value of the pixel. Otherwise, an alternate interpolation process, such as vertical interpolation, is used to estimate the pixel value for the pixel.

  • Patent number: 8553293
    Abstract: An image interpolation apparatus includes an extracting unit, temporal interpolation calculators, pattern matching units, and an output unit. The extracting unit extracts pixels around the missing pixels in order to form a basic frame and comparative frames. Each temporal interpolation calculator corresponds to each comparative frame, and calculates a temporal interpolated pixel for each comparative frame based on signal levels and variation of the signal levels. Each pattern matching unit corresponds to each comparative frame, inserts the temporal interpolated pixel of each comparative frame to the missing pixel, calculates difference of between each of the pixels in the basic frame and each of the corresponding pixels in the comparative frame, and sums up the differences for all pixels in absolute value to obtain sums for all comparative frames respectively. The output unit outputs the temporal interpolated pixel having a minimum sum among the sums as a final interpolated pixel.

  • Patent number: 8537278
    Abstract: In particular embodiments, a process relating to the creation of a high-resolution video from a low-resolution video. In a particular embodiment, the process receives as input a sequence of low-resolution video frames. The process first determines a matching score for consecutive frames in the sequence, where the matching score is based on a preliminary global transformation between consecutive frames. From the matching scores, the process determines a set of matching windows and relative-motion estimates and then uses the set and estimates to calculate more thorough global transformations and any residual relative-motion which can be explained using independent object motion and/or optical flow. The process uses the latter global transformation and any independent object motion and/or optical flow to create motion trajectories and to generate high-resolution frames by interpolating low-resolution frames at trajectory-defined points, using regular-to-irregular spatio-temporal interpolation.

  • Patent number: 8493513
    Abstract: Techniques and tools for high accuracy position calculation for picture resizing in applications such as spatially-scalable video coding and decoding are described. In one aspect, resampling of a video picture is performed according to a resampling scale factor. The resampling comprises computation of a sample value at a position i, j in a resampled array. The computation includes computing a derived horizontal or vertical sub-sample position x or y in a manner that involves approximating a value in part by multiplying a 2n value by an inverse (approximate or exact) of the upsampling scale factor. The approximating can be a rounding or some other kind of approximating, such as a ceiling or floor function that approximates to a nearby integer. The sample value is interpolated using a filter.
