A method for identifying a signaling state of at least one signaling device including a traffic light includes obtaining at least one image which includes an image of the at least one signaling device, extracting a region of the at least one image which includes the image of the at least one signaling device, detecting the at least one signaling device within the extracted region of the at least one image, and detecting a signaling state of the signaling device after detecting the at least one signaling device within the extracted region.

Method and device for identifying the signaling state of at least one signaling device

A scalable encoding apparatus that determines a motion mode of an enhanced layer using motion information of a base layer in a scalable video coding having a structure of the base layer and the enhanced layer. The scalable encoding apparatus includes: a second image detector that detects a current image frame from images input to the enhanced layer; a second motion detector that assigns weight to motion modes of a macro block and macro blocks adjacent to the macro block of the current image frame based on motion mode information and motion vector information obtained from the current image frame of the BASE LAYER, determines motion modes for the current image frame of the enhanced layer by applying the weight and comparing a sum of calculated mode values and a plurality of thresholds, and detects the corresponding motions; and a second motion compensator that compensates the motions detected in the second motion detector to compress the current image frame.

A method of fast mode decision of an enhancement layer using a bitrate-distortion cost in an SVC encoder includes: calculating a bitrate-distortion cost for a current macro block of an enhancement layer and a bitrate-distortion cost for a previous macro-block of the current macro block of an enhancement layer based on an optimal motion mode and an motion vector for a macro block of a base layer of a current frame; correcting the bitrate-distortion cost for the previous macro block calculated at the calculating by a correction value for reflecting relationship with the previous frame to calculate a final bitrate-distortion cost for the previous macro block; and comparing the bitrate-distortion cost for the current macro block calculated at the calculating with the final bitrate-distortion cost calculated at the correcting and selecting a motion mode that will be removed from the current macro block according to the comparison result.
