20090245689 | METHODS AND APPARATUS FOR VISUAL SUB-BAND DECOMPOSITION OF SIGNALS - Methods and apparatus for image processing include performing visual sub-band decomposition of an image using human visual system characteristics to generate a plurality of sub-band decomposed images, independently processing the plurality of sub-band decomposed images with at least one application, and fusing the independently processed sub-band decomposed images to reconstruct an output image. | 10-01-2009 |
20090274386 | METHODS AND APPARATUS FOR IMAGE RESTORATION - Methods and apparatus for restoration of a digital image. In one embodiment, a method for repairing a defect in a digital image to provide a restored image comprises determining a plurality of pixel locations to form a neighborhood relating to the defect and whether or not the neighborhood has a well-defined, dark border along its edge. Should the neighborhood not have dark border, one embodiment of the method entails processing the neighborhood to bring the neighborhood approximately to uniform darkness, processing the neighborhood to match surroundings in the digital image, copying an edge of a neighborhood in the digital image into the processed neighborhood, processing pixels of the edge to repair the copied edge pixels, and outputting the restored image for display to a user. Should the neighborhood have a dark, well-defined border, one embodiment of the method entails processing the neighborhood as to locally enhance the neighborhood and match its surroundings in the digital image; processing the neighborhood's edge such that the edge also matches its surroundings in both the defect and the digital image; processing the neighborhood to invert its pixel values and then perform the last two steps once again; processing the neighborhood to increase its contrast and then perform the last three steps once again; processing the neighborhood to bring the neighborhood to a more uniform darkness; processing the uniform darkness neighborhood to match surroundings in the digital image; and outputting the restored image for display to a user. | 11-05-2009 |
20100263244 | Labels and taggants with programmable multi color coded timing - The objective of the present invention is providing autonomous timing labels for indicating the aging and expiration of a time period of products through gradual changing of their color. The color change can be coded to run, for example, from blue for newly produced products to red with product aging thus allowing easy monitoring, quick identification, and visual warning when the elapsed time approaches and reaches the recommended or safe use time. Said labels comprise thin films of photonic bandgap materials such as cholesteric liquid crystals containing photoisomerizable molecules that are transformed into the state of isomers possessing with finite lifetime with the aid of exposure of the material to UV light. The change of the reflection wavelength of the photonic bandgap material takes place according to changing concentration of said isomers as a result of spontaneous relaxation to their equilibrium state. Said labels can be reused by UV light exposure. The invention has wide applications for time coding of information carriers such as badges, telephone, credit, and gift cards, electronic keys, product labels, shipping tags, storage tags, parking stickers or oil-change stickers for cars, and other carriers of information that are changing as a result of use or storage, and compliance indicators for medical, health, security, and other industries. | 10-21-2010 |

20110228973 | Methods and systems for digital image security - Methods and systems for securing digital imagery are provided. In one respect, embedding, compression, encryption, data hiding, and other imaging processing techniques and systems may be provided for digital image security. In one non-limiting example, a method for producing a compressed and encrypted image is provided. An image may be converted into a binary bit stream, and the bit stream may be decomposed into a plurality of segments. A binary sequence based on a first key may be generated and may be used to generate a code matrix. A distance between the code matrix and the distance may be determined for each of the plurality of segments. Using a combined first and second key, a compressed and encrypted image may be obtained. | 09-22-2011 |
20150086013 | SYSTEMS AND METHODS FOR SIMULTANEOUS COMPRESSION AND ENCRYPTION - Embodiments of reversible systems and methods for fast, secure and efficient transmission, storage, and protection of digital multimedia are disclosed. The embodiments may have the ability to simultaneously compress and encrypt digital data in order to concurrently reduce data size and prevent reconstruction without the proper encryption key. Embodiments of a method may include pre-processing data to optimize the size of data segments to be compressed, transforming the data for improving the compressibility of the before-mentioned data segments, processing the data sequentially to generate predictive statistical models, encoding the data for simultaneously encrypting and compressing data segments using a keystream, and increasing both the compression ratio and security of these encoding processes using a block cipher. Embodiments of these methods may be suitable for use on both encrypted and unencrypted media. | 03-26-2015 |
