System and method to view crash dump information using a 2-d barcode
In some embodiments, the invention involves a system and method for the generation and use of a compact crash dump that can be viewed and/or captured as a two-dimensional (2-D) high contrast graphical barcode. When an error is detected, machine context and other relevant information is formatted for entry to a barcode generator unit. The barcode generator unit received formatted text or codes, and outputs a 2-D barcode for visible capture. The barcode image is ultimately transformed into an electronic image which may be sent to an error reporting site, or individual. The error reporting site uses a decoding unit to decode the high contrast graphical image of the 2-D barcode. The resulting decoded information provides an analyst, or automated system with information relevant to debugging the error. Other embodiments are described and claimed.

Method of generating an animated video sequence
A method for generating an animated video sequence comprises obtaining (100) a photographic image of a scene and determining (102) a projection function of the photographic image, wherein the projection function maps the three-dimensional scene onto the two-dimensional photographic image. A three-dimensional model of an animated object is obtained (104) and the animated object is transformed (106) into a series of two-dimensional object images based on the obtained projection function. The two-dimensional object images are then merged (108) with the photographic image.

System and method for machine vision analysis of an object using a reduced number of cameras
A system and method for analyzing an object using a reduced number of cameras and/or a reduced number of acquired images. The system and method may be utilized in a machine vision application, e.g., in order to inspect manufactured objects. The method may operate to acquire an image, or a plurality of images, of the object. In order to reduce the number of images that need to be acquired, at least one of the acquired images includes visual information for two or more sides of the object. Such an image may be acquired by a camera positioned in any of various ways such that the camera can capture visual information for multiple sides of the object. The acquired images of the object may then be received by computer systems connected to the cameras and analyzed using image processing software. For each image that includes visual information for multiple sides of the object, analyzing the image may comprise determining regions of interest within the image, wherein each region of interest corresponds to one side of the object. Each of these regions of interest may then be analyzed separately. In a machine vision manufacturing application, the results of the image analyses may be used to determine whether the object meets desired production standards. The images or ROIs may be analyzed using any of various techniques or algorithms designed to detect any of various characteristics or defects of the object.

Model based image editing and correction
A system and method is described for automatically editing digital images. An image to be edited is selected and registered with a model that is an abstract of features and attributes common to a category of images to which the selected image belongs. In the illustrated embodiment, a human face is used as an example of an image to be edited and the matching model is a representation of features and attributes common to all human faces. Many other images of objects may also be edited using the techniques of the invention, as long as a general class of objects to which an image belongs is amenable to being represented by a model comprising a set of common features or attributes. A library of different models is available to the user for selecting the model matching the image to be edited. The library includes different models of the same object in different orientations and may also include models of different objects. After the appropriate model is selected, the user is prompted to register the details of the selected image with the generalized features and attributes of the selected model. Editing processes or tools, which are linked to the model, are then automatically appled to the image in order to perform a desired editing function. In addition to applying editing techniques to existing images in a larger image, the invention enables a user to paste and blend images into another, larger image--e.g., create a morphing effect by pasting one persons head over the head of another in an original image.

A three-dimensional photographic technique comprises scanning the outside surface of the three-dimensional surface such as a human subject using a color digitizer which generates spatial and color data relating to the outside surface. The spatial data is used to generate a mold having a concave surface corresponding to the outside surface of the subject. A thin hollow shell of transparent plastics material is molded in the mold to define an outer surface of the shell which corresponds to the outer surface of the subject. The photographic material is applied on the inside surface of the hollow shell and is exposed using an image manipulation system and fiber optic transportation system which extracts the light from a screen and transmit it to a position adjacent the outside surface of the hollow shell to provide the required colored image on the photographic material for display through the transparent material of the hollow shell.
