Digital Signal Processing
Signal is a detectable energy (voltage or current or field strength) which carries information.
Various types of signals are defined here.
Definitions of several systems that used in DSP.
Convolution is the most important and fundamental concept in signal processing and analysis.
By using convolution, we can construct the output of system for any arbitrary input signal, if we know the impulse response of system.
RGB color image can be converted into the gray scale image with a weighted sum of each color component. It describes a fast conversion formula from RGB to gray scale.
Histogram is a graphical representation of data distribution.
Histogram is used to enhance the image contrast or to determine the threshold values for region segmentation.
