This is a program to calculate the Photonic Bands of two dimension Photonic Crystal with circular inclusions. It calculates both TE and TM modes (E and H polarization).
CBUF.LIB
OVERVIEW: The circular buffers here are standard rotating FIFO buffers.
THey are currently used by the RS232 serial library to store
incoming and outgoing data, but they are general purpose.
Circular Convolution of two equal-length vectors. Highlights that circular convolution in the time domain is the effectively the same as element-by-element multiplication in the frequency domain.
eye matching using Circular hough transform for eyedetection and precise eyes location. it is a very good code that works on both grayscale and jpg image.
