iutils is a collection of Python utility codes, encompassing various topics, that I have written, regularly use and update for my own research work.

• Optics (iutils.optics) - Fourier optics, geometric optics, beam optics, colormaps designed for rendering PSFs
• Signal processing (iutils.signal) - Function for several basic signals and transforms
• Computer vision (iutils.cv) - Various geometric transformations such as affine transformation, homography computation, etc.
• Computer graphics (iutils.cg) - Rigid body transformations using Euler angles
• Image processing (iutils.image) - Various image processing utilities, especially image I/O related
• Maths (iutils.math) - Various math utility codes, for array processing, geometry, etc.
• Plotting (iutils.plot) - Utilities for plotting using Mayavi and Matplotlib, colormaps viewer, domain mapping, viewing complex functions, image comparator, etc.
• Miscellaneous utilities (iutils.pyutils) - Utility functions written in Python; E.g., comparing floats, finding Nones in Lists, display utilities, simple tkinter message box, nbconvert in directory etc.

The code is not meant to be production quality. However, the work, and I strive to write as well as I can. Please feel free to use it if you find any of them useful for your own work. Both performance and general accuracy of the code is not guaranteed.

Most of the code here is written by me, but wherever I have borrowed ideas, I have cited the source appropriately.
