摘要： The present disclosure generally relates to systems and methods for image data processing. In certain embodiments, an image processing pipeline may compute noise statistics associated with image data by receiving a frame of the image data having a plurality of pixels. The image processing pipeline may then identify a plurality of portions of the frame of the image data such that each portion of the plurality of portions has a flat surface. The image processing pipeline may then calculate a plurality of gradients for each portion of the plurality of portions, determine one or more dominant gradient orientations for each portion of the plurality of portions, and generate a histogram that represents a plurality of dominant gradient orientations that corresponds to the plurality of portions. After generating the histogram, the image processing pipeline may store the histogram, which may represent the noise statistics, in a memory.

摘要： The invention provides a method for a sender to send a message on a tangible medium and ensure that it is privacy protected until verification that the medium has been received by the authorized recipient. The invention provides a method in which a sender creates an encrypted content message that may be decrypted using a content decryption key that is unknown to the authorized recipient. The sender creates an encrypted authentication message that may be decrypted using a recipient's key that is known to the authorized recipient but is unknown to others, except perhaps to the sender. The sender fixes the encrypted content message and the encrypted authentication message onto a tangible medium and then permits the authorized recipient to obtain the tangible medium. The authorized recipient uses the recipient's key to decrypt the encrypted authentication message and then creates a valid reply that is based upon or which uses the decrypted authentication message. The authorized recipient sends the valid reply to the sender and upon verification that the reply is valid the sender allows the authorized recipient to obtain the content decryption key. With the content decryption key, the authorized recipient is able to decrypt the encrypted content message. The invention also includes an article of manufacture for sending an encrypted message from a sender to an authorized recipient using a method, of the invention.

摘要： A system and method of transmitting an image adapted to a first display area size, such as a standard computer screen having a particular pixel-by-pixel resolution, to an apparatus having a smaller second display area size by scaling the image through coefficient cropping its frequency domain representation. When the cropped frequency coefficients are used to display an image within the second smaller display area, a scaled version of the image is displayed. In a specific embodiment, frequency domain coefficients are cropped such that a region of interest of the image is scaled down less than the remainder of the image when displayed in the second smaller display area. Scaling in this manner provides the user with a readable region of interest with the remainder of the image scaled down so as to facilitate easy image navigation by the user.

摘要： Traditional techniques such as filtering and edge enhancement have been applied to restoring images that have been distorted due to lossy image compression. However, these techniques have ignored a unique feature that can be exploited when working with digital compression. Before the image is stored or transmitted, the sender has access to both the original and the distorted images, enabling the encoder to transmit information specifying the regions where the enhancement was successful. To utilize this feature, before storage or transmission the sender produces a codec file, and assesses the efficacy of one or more enhancement schemes. To determine which image regions have been improved by the enhancement, the enhanced codec is compared to the original. A map of where the enhancement scheme was successful is encoded into the image by making tiny adjustments to the image itself. This method can comply with many compression standards, adds nothing to the compressed images' bandwidth, and distorts the image by only a very tiny amount. Examples are presented showing the reduction of distortion if enhancement is used, together with calculations of how much distortion is introduced if a standard decompressor is used.
