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.

Embodiments of the present invention provide a method, system and computer program product for digital imagery capture in an ad hoc location for mobile computing devices. In an embodiment of the invention, a method for digital imagery capture in an ad hoc location for mobile computing devices can be provided. The method can include determining a geographic position of a mobile computing device disposed in an ad hoc location and identifying at least one image capture sensor proximate to the determined geographic position. The method also can include directing a selected one of the image capture sensor or sensors to acquire imagery. Finally, the method can include wirelessly forwarding the acquired imagery to the mobile computing device.

The primary issue regarding the transmission of digital video to automobiles is limited bandwidth. To help combat bandwidth issues, compression techniques have been developed to reduce the high bit rate required for transmission and storage. However, methods for improving the perceived quality of digital imagery, particularly at low bit rates, are critical. The present invention discloses a technique that will improve the perceived quality of digital imagery to the viewer by using selective post-processing of decompressed digital video. The human visual system (HVS) is very sensitive to human eyes and faces. Regions of interest (ROI), such as human eyes or faces, are selectively post-processed in appropriate video frames prior to being displayed to the viewer. If a subject's eyes are sharp, the viewer will perceive good image quality, despite poor rendition elsewhere. If the subject's eyes are blurry or poorly rendered, the frame will appear poor to the viewer, despite sharpness elsewhere.

The present embodiments, discloses a system and method for generating an aesthetic appliance including a clinical site having a plurality of imaging devices to capture digital imagery of a patient. A computing device receives the digital imagery and transmits the imagery, via a network, to an aesthetic appliance production site. The aesthetic appliance production site includes an aesthetic appliance production device configured to produce the aesthetic appliance.

The present invention provides a method for decoding corrupt codestreams for encoded digital imagery and video and, in particular, JPEG2000 codestreams with improved error resilience properties. The decoding techniques apply to a class of coding algorithms in which the data from underlying images are partitioned, typically to allow decoding of different spatial sections of the image, and the rules governing the dependencies within and perhaps between partitioned sets are known. Corrupt codestreams are decoded with improved image quality by observing the partitions imposed by the underlying algorithm (200), detecting an error in a partition set (202), analyzing the dependencies within and perhaps between the partitions (204), determining what sections of encoded data that follow the error in the partition set can be salvaged (206), and decoding those sections (208). Even though there might be errors in a particular partition, portions of that partition might still be completely or partially decodable, depending on certain modes or “switches” used during the creation of the codestream.

The invention disclosed consists of a process that consists of the steps capturing and collecting digital images of original art works, sorting those images into working sets or groupings, distributing and displaying the digital imagery of the sets or groups in a number of commercial venues and private residences via a slide show utilizing high-resolution video media including television sets and projection onto walls or screens. This process will serve to 1) expose artists' works to a broad audience widely distributed throughout a broad geographic area, 2) entertain its audience; and 3) introduce that audience to dazzling new "high-definition' displays, generally defined as having XGA resolution or higher.

Systems and methods for rapidly developing annotated computer models of structures and properties is provided. The system generates three-dimensional (3D) models of structures and property using a wide variety of digital imagery, and/or can process existing 3D models created by other systems. The system processes the 3D models to automatically identify candidate objects within the 3D models that may be suitable for annotation, such as roof faces, chimneys, windows, gutters, etc., using computer vision techniques to automatically identify such objects. Once the candidate objects have been identified, the system automatically generates user interface screens which gather relevant information related to the candidate objects, so as to rapidly obtain, associate, and store annotation information related to the candidate objects. When all relevant annotation information has been gathered and associated with model objects, the system can create a list of materials that can be used for future purposes, such as repair and/or reconstruction of real-world structures and property. The system also allows for modeling of water damage of a structure, as well as generating lists of tasks for mitigating the water damage and associated costs.

Methods for evaluating one or more immature ears of maize are presented in which digital imagery and image processing are used to assess physical properties of immature maize ears that are correlated with yield and other yield-related traits. Also provided are methods for identifying leads using immature ear photometry.

Motion pictures or other digital media content can be encoded with visible, yet obscured, digital codes that can be optically detected by a camera or other automated image processing device. If a code is recognized in captured media content, further capture, playback and/or distribution can be halted, as desired. Because the code is visible (albeit hidden) in the digital imagery itself, capture by another camera or other optical device will not typically negate the usefulness of the code. That is, the code is visibly present within the imagery itself, so subsequent capture of the video imagery will also capture the code, thereby allowing for detection and/or prevention.

Various examples are provided related to identification of anthropometric information for fitting of compression garments. In one example, a method of generating compression garment fit information includes acquiring images including a selected body part or body area in need of compression therapy; processing the acquired images along with a library of compression garment fit information; generating a 3D reconstruction of the selected body part/area; deriving anthropometric information for the selected body part/area from the 3D reconstruction; providing a compression value corresponding to a prescribed or intended amount of compression therapy applied to the selected body part/area; and generating compression garment fit information for the selected body part/area. In another example, a library of compression garment fit information includes anthropometric information generated for individuals in need of compression therapy; information associated with a health condition for the individuals; and compression garment fit instructions provided by a compression garment manufacturer.

A system, method, and apparatus for vehicle brake monitoring are disclosed. An example method includes receiving three dimensional imagery of a vehicle brake and recording, via a digital interface card, the imagery with and without the brake applied. The method also includes processing, via a processor, the digital imagery samples into a real-world distance measurement of brake components with and without the brake applied. The method further includes applying, via the processor, feature matching to compare the brake component travel distance with at least one measurement recorded previously and stored in a database. The method moreover includes, conditioned on significant changes from that previously recorded measurements, transmitting via the processor, an alert that problems may exist with the sampled vehicle brake.
