Abstract: A system for analyzing velocity distribution of water flow includes a water outlet, a thermographic camera and a processing device. The water outlet is disposed above a water body for discharging sample water thereto, the sample water having a temperature higher than that of the water body. The thermographic camera is disposed above the water body for capturing first and second thermographic images of the water body at different time instances after the discharge of the sample water. The processing device calculates a flow velocity of the sample water in the water body based on the first and second thermographic images, and to analyze the velocity distribution of the water body according to the flow velocity of the sample water.

Abstract: The present invention provide an automatic, frame-by-frame, rapid, and accurate search method for video clip. It comprises the following steps. First, acquire and store a plurality of videos to a storage unit. Each video comprises a plurality of frames, respectively. Then, a processing unit extracts the characteristics of the plurality of frames and gives a plurality of characteristic values. Next, the processing unit calculates a plurality of difference values between the characteristic value of each frame and that of the previous frame and between the characteristic value of the subsequent frame and that of the current frame. Store a data set, which is produced by corresponding the plurality of difference values between all frames of each video to the time axis, to the storage unit. Finally, the processing unit compares a data set of any video with a plurality of data sets of other videos and gives a search result.

Abstract: The present invention relates to a method for size estimation by image recognition of a specific target using a given scale. First, a reference objected is recognized in an image and the corresponding scale is established. Then the specific target is searched and the size of the specific target is estimated according to the acquired scale.
