Image processing apparatus, image capturing apparatus, image processing method and storage medium
A distance measurement accuracy is improved without increasing power consumption of an image processing apparatus that performs distance-measuring processing. In one embodiment, an image processing apparatus for calculating distance information on an image has a reliability calculation unit 113 configured to calculate reliability in accordance with contrast for each pixel of the image and a distance calculation unit 116 configured to calculate distance information on each of the pixels based on reliability of each of the pixels. The distance calculation unit 116 calculates the distance information about a second pixel group whose reliability is lower than that of a first pixel group by using a collation area whose size is larger than a predetermined size in a range in which an amount of calculation in a case where a collation area of the predetermined size is used for all the pixels of the image is not exceeded.

Driver assistance for a combination
For driver assistance for a combination (8) with a motor vehicle (9) and a trailer (10), a first camera image (19) and a second camera image (20) are generated. A combined image (21) is generated by means of a computing unit (13) by superimposing the camera images (19, 20) such that the second camera image (20) covers a subsection of the first camera image (19), wherein a hitch angle (14) of the combination (8) is determined by means of the computing unit (13). State data of the combination (8) are determined by means of a sensor system (17) and it is determined whether the combination (8) moves forward or backward. The hitch angle (14) is determined based on the state data, if the combination (8) moves forward and based on a change of time-dependent image data, if the combination moves backward. A position of the subsection is determined depending on the hitch angle (14).

Learning highlights using event detection
A highlight learning technique is provided to detect and identify highlights in sports videos. A set of event models are calculated from low-level frame information of the sports videos to identify recurring events within the videos. The event models are used to characterize videos by detecting events within the videos and using the detected events to generate an event vector. The event vector is used to train a classifier to identify the videos as highlight or non-highlight.

Occupancy Grid Calibration
A computer-implemented method and system for calibrating an occupancy grid mapping a vehicle environment are disclosed. An example method includes identifying a feature of an occupancy grid that maps a vehicle environment in which the occupancy grid provides a primary representation of the feature. The example method also includes determining a quality level of the primary representation of the feature and determining if the quality level satisfies a quality criterion. The example method further includes adjusting a calibration of the occupancy grid if the quality level fails to satisfy the quality criterion. The adjustment of the calibration of the occupancy grid can include adjusting at least one parameter used to generate the occupancy grid to cause the quality level to satisfy the quality criterion.
