Obstacle detection having enhanced classification

A method and system for sensing an obstacle comprises transmitting an electromagnetic signal from a mobile machine to an object. A reflected electromagnetic signal is received from the object to determine a distance between the object and the mobile machine. An image patch is extracted from a region associated with the object. Each image patch comprises coordinates (e.g., three dimensional coordinates) associated with corresponding image data (e.g., pixels). If an object is present, image data may include at least one of object density data and object color data. Object density data is determined based on a statistical measure of variation associated with the image patch. Object color data based on the color of the object detected with brightness normalization. An object is classified or identified based on the determined object density and determined object color data.

White balance adjustment device and color identification device

The present invention is directed to improving the accuracy of white balance adjustment. An image input from an image capture device 10 is divided into blocks, and white balance gains are calculated from a representative value of each block. Prior to calculation of the representative value of each block, a color range determining circuit 13 determines whether each pixel included in each block belongs to a light source color range, or belongs to an apparent object color range. A representative value of that block is calculated from remaining pixels other than pixels determined to belong to the apparent object color range. Thus, by preventing the representative value from being affected by an object color, the accuracy of white balance gains is improved.

Apparatus and method for obtaining object-color component data

First image data is obtained by performing an image capturing operation with a flash and, subsequently, second image data is obtained by performing an image capturing operation without a flash. By using data of a differential image between the first and second image data and a relative spectral distribution of flash light, the spectrum reflectivity in a position on a subject corresponding to each pixel is obtained and object-color component data is acquired as data from which an influence of an illumination environment has been removed. On the other hand, illuminant component data indicative of spectral distributions of a plurality of illumination light are prepared. By combining arbitrary illuminant component data to the obtained object-color component data, an image with a different illumination environment can be reproduced.

Image processing apparatus and method, and image processing system

If only a specific color and its nearby colors of image data are adjusted, density discontinuation occurs in the image as a whole. If masking is performed to avoid this problem, the adjustment range cannot be bounded, so the processing time increases. On an adjustment parameter designating unit, a user designates, as parameters, a reference color, the adjusted value of the reference color, and an adjustment region in a color space. A coordinate transformer transforms the coordinates of image data as an element of a color correction table, on the basis of a transformation matrix for transformation to an object color space. This transformation matrix is formed on the basis of the parameters by a transformation matrix calculator. If a region determinator determines that the image data is in the adjustment region, an adjusted value calculator calculates an adjusted value on the basis of the parameters.

Realtime object tracking system

A real-time computer vision system tracks one or more objects moving in a scene using a target location technique which does not involve searching. The imaging hardware includes a color camera, frame grabber and processor. The software consists of the low-level image grabbing software and a tracking algorithm. The system tracks objects based on the color, motion and / or shape of the object in the image. A color matching function is used to compute three measures of the target's probable location based on the target color, shape and motion. The method then computes the most probable location of the target using a weighting technique. Once the system is running, a graphical user interface displays the live image from the color camera on the computer screen. The operator can then use the mouse to select a target for tracking. The system will then keep track of the moving target in the scene in real-time.

System and Method of Adjusting the Color of Image Objects Based on Chained Reference Points, Gradient Characterization, and Pre-stored Indicators of Environmental Lighting Conditions

The invention relates to a system and method for adjusting the color of image objects based on chained reference points and / or light gradients to account for the effects of lighting conditions that can vary across different environments, according to an implementation of the invention. To chain reference points and / or characterize light gradients, the system may determine a color shift value, which represents the effects of lighting conditions of a target environment (in which the lighting conditions may be unknown) relative to a reference environment (in which the lighting conditions may be known). The chained reference points, gradient characterization, color shift values, and / or other information may be used to store a delta map that characterizes the lighting conditions of an environment so that it may be reused for subsequent color shifts without re-characterizing the environment.

Adjustment object color space containing movement source partial color space including a color of an object of conversion processing and movement destination partial color space including a color in which the conversion processing is performed so as to inscribe the spaces is handled as a conversion object region. The inside of the conversion object region is moved toward a target color so that coordinates of an adjustment object overlaps with coordinates of a point after movement and the boundary of a movement region moves little or does not move at all. As a result of this, a phenomenon such as a color jump or gradation inversion occurs little in the boundary portion to the outside of an adjustment object region. Therefore, maintenance of gradation continuity of an image of a color adjustment object and prevention of color inversion can be combined to make partial color adjustment.
