To summarize an input image, an image summarization system extracts a background frame and object information of each of objects from an image stream, and selects objects which match a selection condition among extracted objects as a queue object. The image summarization system generates a summarized video based on the queue object and a background frame.

Image summarization system and method

To summarize an input image, an image summarization system extracts a background frame and object information of each of objects from an image stream, and receives a region of interest set in a predetermined region of the background frame. The image summarization system selects the extracted objects as queue objects, and generates a summarized video based on the queue object, the background frame, and the region of interest.

The disclosure is related to monitoring data traffic of user equipment through a monitoring node. A monitoring node may receive a data packet from user equipment registered for a monitoring service through a secure channel. The monitoring node may perform a monitoring operation on the received data packet and determine whether the received data packet is a malicious packet or a non-malicious packet. When the received data packet is a non-malicious packet, the monitoring node may transmit the data packet to a destination through a communication network.

Described embodiments provide an apparatus for providing a digital image by embedding recovery feature. The apparatus may include an input unit, an extraction unit, an embedding unit, and an output unit. The input unit may be configured to receive a digital image. The extraction unit may be configured to extract recovery feature from the received digital image using quad-tree decomposition. The recovery feature may be binary data that represents unique characteristics of the received digital image. The embedding unit may be configured to embed the extracted recovery feature into the received digital image. The output unit may be configured to output the digital image embedded with the recovery feature as a feature hidden image.
