Abstract: A server generates an image with searchable information from a website and transmits that image to a client device. Since the image may be large, the image is generated and transmitted in the background as the client device browses the website. When the client device requests information from the website, the client device first checks if that information has already been transmitted to it in the image as encoded format. If the client device has this information, which is locally stored, then the client device decodes that portion of the image and retrieves the requested information without ever having to contact the server. If the client device does not have this information stored locally, then the client device contacts the server and retrieves the information. Since the image can contain all of the searchable information of a website, the searching process will become faster as time passes.

Abstract: This disclosure pertains to novel devices, methods, and computer readable media for performing color defringing on image data. In photography, particularly RAW images, different artifacts can affect the quality of the edges of objects in the image. This effect is generally more noticeable when the edge has high contrast. One motivation for the described techniques is the understanding that, typically, not all pixels of an image exhibit color fringing. Usually, fringing only occurs in high-contrast edges. Mere masking of the effects of the whole-image operations can improve the result, but further improvements are still possible. This disclosure also pertains to novel devices and computer readable media for performing red-blue color reconstruction on data from a variety of color filter arrays (CFAs).
