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.

Method for size estimation by image recognition of specific target using given scale

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.

Method and system for analyzing velocity distribution of water flow in a water body

In a method for monitoring water level of a water body, a monitoring system is configured to: capture a current image that has a portion of the water body, and a remaining portion aside from the portion of the water body; process the current image into a processed image that includes a water body region corresponding to the portion of the water body, and a background region corresponding to the remaining portion of the current image; mark, on the processed image, a plurality of virtual alert points according to a predetermined water level of the water body; determine whether at least one of the virtual alert points is located within the water body region of the processed image; and generate a monitoring result according to the determination thus made.

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.

Search method for video clip

A remote control method of tile display is disclosed for a tile display system, which contains a host computer, several projector modules, and a screen. The images produced by the projector modules are simultaneously displayed on the screen as a single image. The remote control method includes the steps of: obtaining setting parameters of each projector using a control program on the host computer via a network; storing the setting parameters of each projector in a storage module of the host computer; simultaneously generating a projector parameter table for each projector; updating the projector parameter table when the parameters of any projector are modified; generating a control message for the corresponding projector according to the new parameter table; transmitting the control message to the corresponding projector via the network; and converting the control message into one recognizable by the projector in order to make corresponding modifications.
