摘要:
Exemplary embodiments are directed to biometric analysis systems generally including one or more illumination sources, a camera, and an analysis module. The illumination sources are configured to illuminate at least a portion of a face of a subject. The camera is configured to capture one or more images of the subject during illumination of the face of the subject. The analysis module is configured to analyze the one or more images captured by the camera to determine an indication of liveliness of the subject and prevent spoofing.

A measurement system (301) for determining surface roughness is shown. A coherent illumination device (303) illuminates the surface of, for example, a component (201) with coherent light. An imaging device (304) obtains an image of speckle caused by the scattering of the coherent light from the surface. A processing device (305) converts the image into a binary image according to a threshold, thereby classifying pixels below the threshold as background pixels and pixels above the threshold as foreground pixels. One or more regions of connected foreground pixels are then identified in the binary image, in which any two foreground pixels in a region are joined by a continuous path of foreground pixels. The total number of regions identified and the number of pixels in the largest region are then evaluated, each of which correlate with surface roughness. An indication of the surface roughness of the surface is then outputted.

Concepts and technologies are described herein for providing raster-based mesh decimation. Generally described, input data defining a model is processed to render the model as a depth map from a multitude of perspectives. By capturing depth map data from a multitude of perspectives, components of the model that are visible from the multitude of perspectives are captured in the depth map data and components that are blocked by the visible components are not captured in the depth map data. Point cloud data is generated by merging the depth map data captured from the multitude of perspectives. Output mesh data is generated by applying a surface reconstruction to the point cloud data. One or more mesh decimation algorithms may be applied to the mesh data. Image data may also be captured from the input data and applied to the output mesh data.

In some embodiments, a first homography, created from two images of a roadway, is decomposed to determine an ego-motion, and the ego-motion is used to adjust a previous estimate of a road plane. The adjusted previous estimate of the road plane is combined with the current estimate of the plane to create a second homography, and the second homography is used to determine residual motion and vertical deviation in the surface of the roadway. In some embodiments, multiple road profiles each corresponding to a common portion of a roadway are adjusted in slope and offset by optimizing a function having a data term, a smoothness term and a regularization term; and the adjusted road profiles are combined into a multi-frame road profile. In some embodiments, road profile information for a predetermined number of data points is transmitted in periodic data bursts, with more than one data point per data burst.

An image processing apparatus or the like is provided, which is able to accurately identify an abnormality in a microstructure of a subject even if a difference in resolution of the microstructure is caused due to a difference in imaging distance. An image processing apparatus 1 includes: an imaging distance estimating unit 110 that estimates an imaging distance to a subject shown in an image; an examination region setting unit 120 that sets an examination region in the image, such that an index indicating a spread of a distribution of imaging distance of the subject shown in the examination region is within a given range; and an abnormal structure identifying unit 130 that identifies, by using texture feature data enabling identification of an abnormality in a microstructure of the subject shown in the examination region, whether or not the microstructure of the subject shown in the examination region is abnormal, the texture feature data being specified according to the examination region.
摘要:
In a method for use in an apparatus displaying an image, an object in the image at least partially marked by a mask is highlighted. Successive selection points located on a line crossing a boundary of the mask represent a path input by a user using continuous movements and correspond to respective reference pixels in the image. An initial reference point where the line crosses the boundary is used as a seed point to successively change an attribute of successive points in the mask centered on the seed point for all mask points corresponding to image pixels surrounding the respective reference pixel and for each of which points the corresponding pixel attribute differs from that of the corresponding reference pixel in the image by no more than a predetermined threshold.
