    Abstract: A scannerless range imaging system employs a technique for embedding digital data into its image output in a manner that allows exact recovery of its associated images. The range imaging system captures (a) a plurality of phase images of reflected modulated illumination, wherein each image incorporates a phase delay term corresponding to the distance of objects in the scene from the range imaging system, together with a phase offset term unique for each image, and (b) at least one intensity image of reflected unmodulated illumination, and then generates an image bundle of associated images including the plurality of phase images and the intensity image. Meta-data is embedded into the image bundle by a) forming a digital message from the meta-data, b) converting the digital message to embedded data, and c) adding the embedded data to each phase image in the image bundle, pixel by pixel, without changing the phase term in each of the phase images, thereby allowing exact reconstruction of range information from the phase images without having to extract the embedded data.

    Abstract: A method for image capture and estimation of range information is provided which uses photographic film as the image capture mechanism. A plurality of identical images are captured on film yielding an image bundle wherein each image in the image bundle is captured with a different phase offset. Fiducial marks are placed on the photographic film between adjacent images in the image bundle. The image bundle is developed and the developed images are scanned. The images of the image bundle are then registered by aligning the fiducial marks. The distance from the image capture device to object(s) in the images of the image bundle can then be estimated using the different phase offsets for each image. The range at a pixel location is estimated by selecting the intensity of the pixel at that location of each image and performing a best fit of a sine wave of one period through the points. The phase of the resulting best fitted sine wave is then used to estimate the range to the object based upon the wave length of the illumination frequency.

    Abstract: A method of encoding and decoding a transaction card with a block of image data digitally representing the features of a digital portrait of an authorized transaction card user is disclosed along with apparatus for performing the method. The encoding method partitions the digital portrait of the transaction card user into feature blocks. Each feature block is compared against a library of like feature blocks to determine the best match with a pair of library feature blocks. The library's feature blocks are derived from a plurality of portraits taken from the general population. Each library feature block is represented (addressed for access) by a code-vector in a codebook. The two code-vectors corresponding to the two closest matching features blocks from the library of like feature blocks are recorded onto a transaction card along with an interstitial pointer which indicates a weight to be allocated to each of the two code-vectors to form a better match for at least one of the library feature blocks to the user's feature blocks. All of the code-vectors and the interstitial pointers corresponding to the user's feature blocks are recorded as a sequence of sub-data blocks within an image data block on the transaction card. A method and associated apparatus for reading out the image data block and recreating a representation of the portrait of the transaction card user at a financial transaction site for identification purposes are also disclosed.
