edgedetection

本书详细讲述了如何用MATLAB进行程序设计，如何编写清楚、高效的程序。书中强调了自上而下的程序设计方法、函数的使用、MATLAB内部工具的使用和数据结构，并指出了一些使用技巧和编程者常犯的错误。(This book describes in detail how to use MATLAB for programming, how to write clear and efficient procedures. The book emphasizes top-down program design, function, use, MATLAB uses internal tools and data structures, and pointed out some tips and common mistakes programmers.)

说明：  络检波法，也可以用同步解调法，现在我们来使用同步解调法，即将已调信号和一个与载波信号同频率的信号相乘，在通过一个理想低通滤波器就可以得到原始信号(Envelope detection method, you can also use synchronous demodulation method, and now we use synchronous demodulation method, is about modulated signal and a signal is multiplied with the same frequency of the carrier signal, through an ideal low-pass filter can get the original signal)

A black body is an idealized physical body that absorbs all incident electromagnetic radiation, regardless of frequency or angle of incidence.Black-body radiation is distributed in energy (or frequency) in a manner set by the temperature T. A black body in thermal equilibrium emits electromagnetic radiation called black-body radiation. The radiation is emitted according to Planck s law, meaning that it has a spectrum that is determined by the temperature alone (see figure at right), not by the body s shape or composition. Practical materials emit energy at a fraction of black-body energy levels called the emissivity of the surface. By definition, a black body in thermal equilibrium has an emissivity of ε = 1.0. A source with lower emissivity independent of frequency often is referred to as a gray body. Construction of black bodies with emissivity as close to one as possible remains a topic of current interest. This code can be used to simulate the black body radiation.
