In a 3D object molding apparatus (10), a tank (18d) holds an uncolored or white resin as a first material for use in interior molding, and tanks (18a to 18c) hold colored resins as second materials for use in surface molding. These resin materials are jetted from injection nozzles (15a to 15d) in the direction of a stage (20). A drive control unit (12) serving as control means moves a nozzle head (15) in the XY plane and controls jets of resin materials from the injection nozzles (15a to 15d). In the interior molding of a 3D molded product (21), at least the first material is jetted, while in the surface molding, at least the second materials are jetted. The injection nozzles (15a to 15c) are coloring nozzles to jet colored resins in molding color portions of the 3D molded product, and the injection nozzle (15d) is a molding nozzle to jet an uncolored molding resin in molding the other portions. The apparatus 10 provided with the coloring nozzles to jet predetermined coloring agents such as colored resins can jet coloring agents from the coloring nozzles in molding the 3D molded product, thereby achieving coloring of the 3D molded product in the molding process. Further, the use of a white resin allows representation of blight colors that are not available only with three colors (Y, M, C), thereby permitting reproduction of the color intensity and gradations in the coloring of the 3D molded product (21) in the molding process.

The invention relates to methods and materials for controlling stability and color intensity in an electrophoretic display element. Filler particles in the electrophoretic display element, serves as a medium that the electrophoretic particles must travel through during switching between optical states of the display. The filler particles provide improved control over the color intensity of the electrophoretic display element. In addition, the filler particles create resistance to the migration of the electrophoretic particles, thereby improving the bistability of the electrophoretic displays and inhibiting settling of the electrophoretic particles. Also, migration resistance provided by the filler particles can enable threshold addressing of an electrophoretic display.

A display provides increased contrast and resolution via first LCD panel energized to generate an image and a second LCD panel configured to increase contrast of the image. The second panel is an LCD panel without color filters and is configured to increase contrast by decreasing black levels of dark portions of images (making them blacker or darker) using polarization rotation and filtration. Preferably, the second LCD panel is of higher resolution than the first LCD panel. The panels may be directly illuminated or edge lit, and may be globally or locally dimmed monochrome or multi primary lights that may also include individual control of color intensities for each image or frame displayed. The panels may be placed in any order, but preferably are arranged such that active layers in each panel are as close together as possible. Brightness is maintained by the combination of reusing polarization between the panels and by not going through more than one set of color filters. Improved contrast is a result of using multiple light modulators in series.

The combined range and color intensity information is combined to produce a single colored pixel in space. Multiple illuminations are used to create multiple pixels which can be combined to produce images. A rotating housing may be used for an entire surrounding image.

A scalable video bitstream may have an H.264 / AVC compatible base layer and a scalable enhancement layer, where scalability refers to color bit depth. The H.264 / AVC scalability extension SVC provides also other types of scalability, e.g. spatial scalability where the number of pixels in BL and EL are different. According to the invention, BL information is upsampled in two logical steps, one being texture upsampling and the other being bit depth upsampling. Texture upsampling is a process that increases the number of pixels, and bit depth upsampling is a process that increases the number of values that each pixel can have, corresponding to the pixels color intensity. The upsampled BL data are used to predict the collocated EL. The BL information is upsampled at the encoder side and in the same manner at the decoder side, wherein the upsampling refers to spatial and bit depth characteristics.

A two step method of coloring hair is described.

A method and computer product are presented for identifying a subject by biometric analysis of an eye. First, an image of the iris of a subject to be identified is acquired. Texture enhancements may be done to the image as desired, but are not necessary. Next, the iris image is radially segmented into a selected number of radial segments, for example 200 segments, each segment representing 1.8° of the iris scan. After segmenting, each radial segment is analyzed, and the peaks and valleys of color intensity are detected in the iris radial segment. These detected peaks and valleys are mathematically transformed into a data set used to construct a template. The template represents the subject's scanned and analyzed iris, being constructed of each transformed data set from each of the radial segments. After construction, this template may be stored in a database, or used for matching purposes if the subject is already registered in the database.

A method for processing a time-ordered sequence of video frames. The method is implemented by execution of program code on a processor of a computer system. Each frame includes a two-dimensional array of pixels and a frame-dependent color intensity at each pixel. A current frame and at least one frame occurring prior to the current frame in the sequence are analyzed via a background subtraction on the at least one frame to determine a background image and a static region mask associated with a static region. The background subtraction determines an existence of a static object relating to the static region. A status of the static object is determined, the status being either that the static object is an abandoned object or that the static object is a removed object. The determined status is stored in a data storage medium of the computer system.

Any issues associated with manufacture of a part are identified and highlighted on a part rendering. A software method and system then uses a visual change cue on the part rendering for communicating the manufacturability issues to the customer. The preferred visual change cue is a throbbing of the highlighting of the manufacturability issue, with the throbbing occurring in both color intensity and size. The part rendering depicts the part translucently, so throbbing manufacturability issues can be readily identified even if obscured behind a more-forward face of the part.
