Abstract: The disclosure provides a method of switching video images and a surveillance system. The method includes the following steps. A first video image is displayed under a first display mode in a monitoring interface. Whether a target object in the first video image enters into a designated region in the first video image is determined. Whether a ratio of the targeted object to the first video image is smaller than or equal to a first threshold is determined when the target object enters into the designated region. When the ratio is smaller than or equal to the first threshold, a second video image is displayed under the first display mode in the monitoring interface. The designated region in the first video image is related to a geographic position, and the second video image is a video image related to the geographic position.

Abstract: Methods and apparatus of compression for non-stitched pictures captured by multiple cameras of a panoramic video capture device are disclosed. According to one embodiment, the system uses a RIBC (Remapped Intra Block Copy) mode, where the block vector (BV) or BV predictor is remapped using calibration data to reduce the search range.

The projection-based Inter prediction method takes into account different perspectives between two images captured from different cameras. Transform matrix is applied to a block candidate to project the block candidate to a position of a target block. The projected block candidate is used as a predictor for the target block.
