The Image Processing and Machine Vision Library (IPL) Electrical Engineering and Computer Science Department University of Tennessee (UT)

Note: This library was initially created in the Fall semester of 2000, used by both the Digital Image Processing and the Pattern Recognition class offered at UT. The goal is to set up a simple programming structure for students to develop and practice algorithms studied in class.

The author thanks the contribution from all students over the years. For bugs and comments, please contact Hairong Qi, [email protected].

The library contains the following files:

###README - this file###

###\include - header files###

• Image.h: defines the new Image class.
• Dip.h: declares various functions for DIP and MV
• Map.h: contains parameters used for MAP

###\lib - library files###

• Makefile: makefile to build the image library
• wt.cpp: 1-D and 2-D wavelet transform (daub4, wt1d, wt2d)
• pointProcessing.cpp: point-based image enhancement routines (negative, cs, logtran, powerlaw, threshold, bitplane, sampling, quantization, histeq)
• addNoise.cpp: adds different noise distribution to an image (gaussianNoise, sapNoise)
• conv.cpp: kernel operation (conv)
• lowpassFilter.cpp: low-pass filters (linear and nonlinear) (average, gaussianSmooth, median, contrah, gmean, amedian)
• freqFilter.cpp: frequency-domain filters (ideal, butterworth, Gaussian, inverse, wiener)
