Abstract: Scalable coding concepts are described. One aspect improves parallel decoding of inter-dependent layers of a multi-layer video data stream by introducing a long-term syntax element structure for guaranteeing that during a predetermined time period the pictures of the dependent layer are subdivided so that borders of the spatial segments of the pictures of the second layer and the spatial segments of the first layer overlay. Another aspect concerns upsampling from base layer to enhancement layer. Another aspect introduces a long-term syntax element structure allowing the decoder to determine the inter-layer offset for a predetermined time period. Another aspect introduces a type indicator field changing a way a layer indicator field within the NAL unit headers is to be interpreted. Another aspect allows different codecs/standards to be used for the different layers. Another aspect concerns a syntax element structure which indicates the inter-layer offset in units of the base layer blocks.

Abstract: In an image processing apparatus, an image acquisition unit acquires an image. A correction unit corrects pixel values of pixels composed of the acquired image by using correction coefficients to produce a correct image. An object recognition unit recognizes an object in the corrected image. A storage unit stores in advance standard color characteristics of a predetermined object which is a recognition target. A color characteristics acquisition unit acquires color characteristics of the predetermined object if the predetermined object is recognized by the object recognition unit. A comparison unit compares the color characteristics of the acquired object with the standard color characteristics of the same predetermined object stored in advance in the storage unit. An updating unit updates the correction coefficients used in the correction unit based on a result of comparison so as to reduce a difference between the color characteristics and the standard color characteristics.

Based on the foregoing and the size and shape of the image portion occupied by the object, such as the height of an edge or its surface area, relative to another object or a reference, the device may calculate its location.

Abstract: For determining positions and orientations of mirrors, the mirrors are illuminated with parallel light rays. A first camera is arranged in an image plane onto which an objective images the mirrors.

Abstract: The present technology relates to an image processing apparatus and method capable of preventing an increase in a cost of the apparatus. A setting unit sets restriction information for restricting a size of a block of an image and a prediction method to be applied to the block having the size. An inter-prediction unit generates a prediction image according to the restriction information. An encoder 1000 encodes the block using the prediction image and generates an encoded stream. Then, the encoder 1000 transmits the encoded stream and the restriction information. The present technology can be applied to a case of encoding/decoding an image, and the like.

Abstract: A process estimates height and tilt of a camera having an image sensor array and IR illuminators. The process identifies multiple distinct subsets of the illuminators. For multiple heights and tilts, the process constructs dictionary entries that correspond to the camera having the height and tilt above a floor. Each entry includes light intensity values for pixels in images corresponding to activating each of the subsets of illuminators. For each of the subsets, the process receives an image of a scene captured while the subset is emitting light and the other illuminators are not. The process uses the captured images to identify a floor region corresponding to a floor in the scene. The process forms a vector including pixels from the captured images in the identified floor region and estimates the height and tilt of the camera by comparing the vector to the dictionary entries.

Abstract: An aerial surveillance and reconnaissance system includes a gimbal-stabilized ISR imaging sensor with 0.8-1.2 microradian optical resolution, using pulsed ultraviolet laser (0.330-0.380 micrometer wavelength) radiation to illuminate the observed target, and a narrow-band-pass filter at the focal plane detector to remove light at frequencies other than the illuminating frequency. Preferred sensors can be operated in a snapshot mode using intermittent illuminating pulses, with timing of the pulses selected for minimum detectability based on observations made with a lower-resolution sensor, or in a video-mode with illuminating pulses selected to generate full-motion video at operator-selectable frame rates. Some sensor embodiments may further combine the UV system described above with conventional daylight optical and sensor systems, though alternative arrangements could also include an IR sensor as well (either using a common aperture with the UV system or with a separate set of light-gathering optics).
