    Abstract: An imager achieves a desired image resolution by successively reproducing partial images which complement each other. The imager assigns pixels from an input image to the respective partial images according to complementing patterns that correspond to the pixel pattern of the imager. The imager reproduces the complementing pattern at different spatial positions, such that the complementing patterns merge. In order to avoid perceived double imaging of moving objects the image signal provided to the imager is assembled from an original image and a motion compensated interpolated image, which is derived from at least two consecutive images. Accordingly, every other partial image that is reproduced is derived from an interpolated image and takes into account movement of objects in the image that takes place between two consecutive images. In one embodiment the partial images are re-combined into one full image in a sequence that anticipates the distribution of the pixels used in the imaging device.

    Abstract: Described is a hierarchical filtered motion field technology such as for use in recognizing actions in videos with crowded backgrounds. Interest points are detected, e.g., as 2D Harris corners with recent motion, e.g. locations with high intensities in a motion history image (MHI). A global spatial motion smoothing filter is applied to the gradients of MHI to eliminate low intensity corners that are likely isolated, unreliable or noisy motions. At each remaining interest point, a local motion field filter is applied to the smoothed gradients by computing a structure proximity between sets of pixels in the local region and the interest point. The motion at a pixel/pixel set is enhanced or weakened based on its structure proximity with the interest point (nearer pixels are enhanced).

    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: 8483516
    Abstract: A super resolution (SR) method or system with database-free texture synthesis is disclosed. An input image is up-sampled to result in an up-sampled image. It is determined whether the input image possesses a smooth region. Edges of the up-sampled image are enhanced, and the enhancing edges step is bypassed if the smooth region has been detected. The enhanced or unenhanced up-sampled image is texture synthesized by taking the input image as texture example, thereby resulting in a synthesized image.

    Abstract: Described herein are a method and system for frame rate adaptation. There may be conditions that require the rate of a video sequence to be dynamically controlled, and a frame interval may be adaptively selected every frame. A frame within the video sequence may contain, for example, a time stamp that is transmitted to a decoder to indicate the change in temporal spacing between frames.

  • Patent number: 8421914
    Abstract: A down-sampling operation is performed on moving image data to reduce a sample count of the data to 1/M times the original sample count. In the down-sampling operation, a band-limitation operation is performed on the moving image data using a low-pass filter. The low-pass filter has a stop band frequency that prevents a harmonic component having a K-th order or higher, of harmonic components generated in the down-sampling operation, from overlapping an original signal component. The down-sampling operation is then performed on the band-limited moving image data, thereby compressing the moving image data. Aliasing distortion caused by a harmonic component of a high order is controlled. The resulting compressed image is free from a substantial loss of a high-frequency component of the original signal.

  • Patent number: 8294819
    Abstract: A de-interlacing method includes the following steps. A de-interlacing pixel datum of a target pixel is obtained according to a current field and multiple correlated fields. A caption region of the current field is defined according to the fields, and a region motion vector and a region confidence are correspondingly obtained. When the target pixel belongs to the caption region, a compensation pixel datum of the target pixel is obtained by motion compensation according to at least a part of the fields and the region motion vector, and the target pixel is judged as a foreground pixel or a background pixel to output a compensation select signal according to the region motion vector and the region confidence. The de-interlacing pixel datum or the compensation pixel datum is outputted as a correlated pixel datum of the target pixel according to the compensation select signal.

    Abstract: A method and a system for determining a video deinterlacing strategy are disclosed. First, all the pixels of a (i+2)th field are subtracted from the corresponding pixels of the ith field to obtain a difference field. Next, a specific check-area is located according to the difference field. Next, the ith field is combined with the (i+1)th field into a specific frame. Next, the combing phenomenon of the specific check-area in the specific frame is checked to determine the deinterlacing scheme for the pixels in the specific check-area.
