The design of heating plate is a typical heat conduction inverse problem about heating source calculation for thermal field of the plate. It's difficult to solve the inverse problem, which is large calculation and low efficiency. This paper puts forward a way to translate heat conduction inverse problem about heating source calculation to an optimization problem to solve, whose optimization target...
A novel method based on optical defocus of imaging system is presented for the estimation of the depth of the 3D scene. Firstly, optical defocus is described using the oriented heat-flows equation based on curvature driven. Secondly, the depth retrieval problem is translated into the minimum problem of energy functional with total variation regularization. Finally, the gradient flow is used to seek...
In order to achieve the maximal diathermanous efficiency, this paper introduces two calculation methods about the most economical diathermanous area of the Shell and tube heat exchanger which works in two different conditions, and establishes the corresponding mathematical models.
The amount of blur on the defocus image depends on the depth information of the scene. So depth of the scene can be estimated by calculating the blur with the knowledge of the lens parameters. A novel depth estimation mode based on oriented heat-flows is proposed in this paper. In this model, the process of image defocusing is described using oriented heat-flows diffusion. The diffusion can be seen...
