Abstract:
PURPOSE: A water level monitoring device and a method are provided to determine a water domain by automatically varying a thread hold value determining water by using a motion factor value, thereby accurately detecting a water level. CONSTITUTION: A water level monitoring device comprises a receiving unit(200), a setting unit(310), and a monitoring unit(330). The receiving unit receives video data from a camera or external devices. The setting unit classifies a monitoring domain into a plurality of unit domains and set some of the monitoring domain as a base domain. The monitoring unit sets one or more seed domains among the unit domains of the base domain and reflects a motion factor value calculated by accumulating the number of video changes per each unit domain to the corresponding unit domains, thereby varying a thread hold value of each domain.

PURPOSE: A forest fire monitoring apparatus using a thermal imaging camera and a method thereof are provided to detect accurately smoke with the unique pattern analysis of the smoke even when the smoke is hidden by fog or cloud, thereby enabling the forest fire to be under control at an early stage. CONSTITUTION: A forest fire monitoring apparatus using a thermal imaging camera comprises a thermal imaging camera (10), a foreground/background division unit (110), an object extraction unit (120), an object tracking unit (130), a pattern storage unit (140), and an output unit (150). The foreground/background division unit receives consecutive thermal imaging data from the thermal imaging camera and divides each thermal imaging data into a foreground image and a background image according to a long-term background modeling mode. The pattern storage unit includes pattern information considering the temperature range, movement direction, or spread of smoke generated by a forest fire. The object extraction unit extracts objects within the temperature range included in the pattern information based on brightness information according to the temperature of objects which is included in the foreground image divided by the foreground/background division unit. The object tracking unit monitors the objects extracted from the consecutive thermal imaging data by the object extraction unit, and outputs forest fire information when an object of which a change of a pixel number or the movement direction satisfies the pattern information is detected.

Abstract:
An image stabilization method and an image stabilization apparatus for performing the method are provided to estimate the motion of a target frame at a smaller cost by calculating the sum of absolute differences between the target frame and a predetermined templet at some positions. The first area is set up. At the locations of pixels of the first area, the sums of absolute differences between a target frame and a predetermined templet are calculated. The minimum value is extracted from the calculated sums. If the location corresponding to the minimum value is at the center of the first area, the displacement of the target frame is precisely estimated within each pixel by using the secondary curve. But, if the location does not exist at the center of the first area, the second area adjacent to the first area is set up.
