    Abstract: An original design image is processed to create a modified design image for blending with an image of a product to create a combined image representing the result of printing the design image onto the product. To create a modified design image, both the alpha value and color of pixels in the original design image are modified. The modified alpha value and the modified color of a pixel are determined as a function of the amount of gray in the original color of the pixel. The modified pixel color is calculated by subtracting the level of gray in the original pixel color from each of the three original component color values and increasing any remaining color component values as a function of the modified alpha value of the pixel.

  • Publication number: 20130100350
    Abstract: The purpose of an objective video quality evaluation is to automatically assess the quality of video sequences in agreement with human quality perception. The invention addresses the effects of the introduction of a temporal dimension by focusing on the temporal evolutions of spatial distortions, since it has been found that a spatial quality variation cannot be evaluated by simple subtraction of the spatial quality of neighbouring frames. An improved method for estimating perceived video quality comprises steps of calculating a first similarity map between adjacent frames of a current sequence, calculating a second similarity map between the corresponding reference frames, and calculating (smg3) a third similarity map, which provides a numerical quality value.

  • Publication number: 20130093949
    Abstract: In general, in one aspect, the frames of a received video are analyzed using traditional film mode detection (continually capturing data and comparing the data to known parameters for various film modes) until a film mode is detected. Once the film mode is detected, the frames of the received video are analyzed using mode based tracking where measurements are continually predicted based on the mode detected and averaged with actual measurements. The use of the averaged measurements limit the effect of noise captured in the actual measurements. The averaged measurements are continually compared to known parameters for the detected mode to determine if the detected mode is still valid. If the detected mode is valid, the mode based tacking is continued. If the detected mode is no longer valid (e.g., averaged measurements not correlated with known parameters), the process returns to the traditional film mode detection.

  • Publication number: 20130016284
    Abstract: What is disclosed is a system and method for image reconstruction using a compressed sensing framework to increase the number of wavelength bands in hyperspectral video systems. The present method utilizes a restricted representation matrix and sampling matrix to reconstruct bands to a very large number without losing information content. Reference multi-band image vectors are created and those vectors are processed in a block-wise form to obtain custom orthonormal representation matrices. A sampling matrix is also constructed offline in the factory. The compressed sensing protocol is applied using a l1-norm optimization (or relaxation) algorithm to reconstruct large number of wavelength bands with each band being interspersed within the band of interest that are not imaged. The teaching hereof leads to very large number of bands without increasing the hardware cost.
