A forward-facing vision system for a vehicle includes a forward-facing camera disposed in a windshield electronics module attached at a windshield of the vehicle and viewing through the windshield. A control includes a processor that, responsive to processing of captured image data, detects taillights of leading vehicles during nighttime conditions and, responsive to processing of captured image data, detects lane markers on a road being traveled by the vehicle. The control, responsive to lane marker detection and a determination that the vehicle is drifting out of a traffic lane, may control a steering system of the vehicle to mitigate such drifting, with the steering system manually controllable by a driver of the vehicle irrespective of control by the control. The processor, based at least in part on detection of lane markers via processing of captured image data, determines curvature of the road being traveled by the vehicle.

An interior rearview mirror system suitable for use in a vehicle includes an interior rearview mirror assembly having a mirror casing and a transflective reflective element. The transflective reflective element has an electrochromic active region, and a plurality of user input elements is disposed outside of the electrochromic active region and below the electrochromic active region. Each of the individual user input elements is a touch or proximity sensor. A plurality of display elements is disposed behind the transflective reflective element at the electrochromic active region, and each display element is selectively activated by activation of a respective user input element. Each of the individual display elements and its associated respective one of the individual user input elements are located local to one another such that a cognitive relationship between actuation by a user of a respective user input element and activation of its associated display element is established.

A display system (100) for displaying images from different data streams (1,2) simultaneously is described. Images corresponding to the first data stream (1 ) are shown to a first observer (106) in a vehicle and images corresponding to the second data stream (2) are shown to a second observer (108) in the vehicle. The display system (100) comprises: a display screen (102) for generating a first one of the images and a second one of the images; and an optical selection screen (104) for selectively passing the first one of the images in a first direction (101) towards the first observer (106) and passing the second one of the images in a second direction (103) towards the second observer (108). It is advantageously that the display screen (102) generates images from both data streams (1,2).

A 3D video conferencing station (200, 300, 500, 700) comprises: a camera (104) for acquiring a first (604) and second (602) image of a first user (110); and optical means for visualizing stereo images of a second user, the optical means comprising glasses for the first user (110). The station (200, 300, 500, 700) is arranged to acquire the first image (604) at a first moment at which the left eye of the first user (110) is better observable by the camera (104) than a second moment and to acquire the second image (602) at the second moment at which the right eye of the first user (110) is better observable by the camera (104) than at the first moment. The station further comprises combining means (714) for combining a first portion of the first image (604) and a second portion of the second image (602) into a third image (606) in which the left eye and the right eye of the first user (110) are relatively well visible.

A mirror assembly (18) for displaying an image (15) in conjunction with the reflection (14´) of a viewer comprises a mirror (2), which is equipped with a reflective polariser (13), arranged to reflect light (3) incident on its viewing side and transmit light (4) incident on its non-viewing side, where the reflected light (3) and transmitted light (4) may be of different polarisation. The image (15) is displayed by a device (5) located on the non-viewing side and focussed by a focussing element, e.g. one or more lenses (12, 12a), onto an image plane. The image plane may be located between the mirror (2) and viewer (14), so that a perceived image (15´) appears to stand out from the mirror (2). Alternatively, the image plane may be located so that the perceived image (15´) forms a background in which the viewer's reflection (14´) is immersed. The mirror assembly (1) may further comprise one or more detectors (19) for obtaining a silhouette (21) of the viewer (14). The silhouette (21) can be subtracted from an image (15) to produce a modified image (24) for display by device (5), thereby avoiding competition between the perceived image (15´) and viewer reflection (14´).

A multi-view image generation unit (100) for generating a multi-view image on basis of an input image is disclosed. The generation unit (100) comprises: edge detection means (102) for detecting an edge in the input image; depth map generation means (104) for generating a depth map for the input image on basis of the edge, a first group of elements of the depth map corresponding to the edge having a first depth value, related to a viewer of the multi-view image, and a second group of elements of the depth map corresponding to a region of the input image, being located adjacent to the edge, having a second depth value, related to the viewer of the multi-view image, the first value being less than the second value; and rendering means (106) for rendering the multi-view image on basis of the input image and the depth map.

Multi-view image generation

Most watermarking schemes are not resistant to geometric distortions of a watermarked image, because such manipulations destroy the correlation between the original watermark and the watermark in the manipulated image. In order to restore the correlation, a suspect image (Q) is analyzed ( 6 ) for the presence of a repeated data pattern. If such a pattern is found, it is concluded that the image has been watermarked by “tiling” a small-sized watermark pattern over the extent of the image. The actual detection of whether the watermark is a given watermark W is subsequently performed by determining the periodicity of the pattern found in the suspect image, and processing ( 9 ) the suspect image so as to match the periodicity of the processed image with the given periodicity of the watermark to be detected. If the suspect image indeed includes the given watermark W, the geometric manipulation is thereby undone and a conventional watermark detector ( 3 ) will signify this accordingly. If a combination of operations can generate the same periodicity, the detection step will include the set of possible combinations.
