A method and a device for augmenting data in a monitoring video are provided which includes: selecting randomly, based on a function to be implemented for the data and a parameter range which are set by a user or by default, one or more processing functions to be performed on the data and parameters of the processing functions; processing the data using the selected one or more processing functions, to obtain new data; and repeating the above processes until a required amount of data is generated. With the method, monitoring data having diversity and a small size can be obtained with only a few input samples, and a high degree of randomness and comprehensiveness of the augmented data can be achieved.

Smoke detection based on video images includes performing background image modeling on a current image, to acquire a foreground image and a background image of the current image; acquiring one or more candidate areas in the current image used for detecting a moving object, based on the foreground image; calculating attribute information of a candidate area corresponding to the current image and/or the background image; and determining whether there exists smoke in the candidate area according to the attribute information. The smoke can be detected quickly and accurately through video images, but also the detection accuracy of video-based smoke detection when light changes and at complex environments can be provided.

Apparatus, method and image processing device for smoke detection in image

A method and system for approximating a curve, and a graphic display control method and apparatus are disclosed. The method for approximating a curve comprises the steps of acquiring number information of subdividing points for subdividing a curve needed to be approximated based on coordinate information of control points of the curve, acquiring coordinate information of the subdividing points based on the number information of the subdividing points and the coordinate information of the control points, and connecting the subdividing points with straight lines based on the coordinate information of the subdividing points. The invention could achieve efficient curve approximation and in turn achieve efficient graphic-display control.
