Abstract: For detecting an obstacle with a camera, a first image is viewed by the camera at a first location during a first time. Points on a surface would project onto first pixels of the first image. A second image is viewed by the camera at a second location during a second time. The points on the surface would project onto second pixels of the second image. Coordinates of the second pixels are identified in response to coordinates of the first pixels, in response to a displacement between the first and second locations, and in response to a distance between the camera and the surface. The obstacle is detected in response to whether the first pixels substantially match the second pixels.

Abstract: Methods and systems for parking lot occupancy determination. Video of an entrance to a parking lot (or other facility) can be acquired utilizing one or more video cameras focusing on a pre-defined vision-based region of interest and a pre-defined video-based region of interest. The video can be video processed via a classifier that is pre-trained to take into account potential camera shake disturbances to generate video output data thereof. The video output data can then be trajectory smoothed. The video output data (following trajectory smoothing) can then be analyzed for parking lot occupancy data such that the impact of camera shake with respect to the video camera(s) is minimized to determine parking lot occupancy.

Abstract: An invention is disclosed for encoding and decoding data in a 4:4:4 subsampling scheme, using an encoder/decoder that is not configured to encode or decode data in 4:4:4. In embodiments, an encoder planararizes an input frame into three component frames in a 4:0:0 scheme. The encoder then encodes each component frame in the 4:0:0 scheme, and aggregates the encoded component frames into a bit stream. A decoder receives such a bit stream, and decodes it with a component not configured to decode data in 4:4:4. The decoder decodes the bit stream to produce a representation of the three component frames in 4:0:0, then aggregates the three component frames into a representation of the original frame in 4:4:4.
