Digital Image Processing Simulator (DIPS) - A Software for Teaching Digital Image Processing Concepts
In writing this software, the author had to avoid the use of special VB controls that would add to the size of the software. In pursuance of the size constraint a simple text file was used to improvise a basic help system. The default data and exercises in various modules were designed to expose different facets of the image-processing concept under study. The screen presentation of each concept covered by DIPS was conceived in a manner such that the concept can be graphically communicated in detail with ease. In addition, screens had to be designed such that calculations for each concept could be seen in a step by step mode.
Concept Coverage
DIPS is primarily aimed at introductory digital image processing courses in remote sensing. DIPS should be of use to University/ College teachers , students undergoing Remote Sensing Courses, and other training organizations. DIPS covers a core body of digital image processing concepts. DIPS has been specifically designed to expose detailed calculations of image processing algorithms using small sample images. The users can change these small sample images to build their own examples and add to the pool of exercises. DIPS covers the following important image processing concepts:
- Additive and Subtractive Primary Colours
- Display of Colour on Multi-band Digital Images
- Gun Band Assignments
- Linear Contrast Stretching
- BSQ,BIL and BIP Digital Data formats
- Line dropout and Salt and Pepper noise removal
- Operation of Low Pass and high pass convolution filters
- Image Ratioing
- Normalized Vegetation Difference Index
- Image Differencing (subtraction)
- Linear Edge Enhancement
- Density Slicing
- Supervised Classification
- Signature Definition
- Minimum Distance to Mean Classifier
- Parallelepiped Classifier
- Comparison of Classification Outputs
- Accuracy Assessment
- Random Selection of Pixels on Classified and Ground maps
- Computation of Error Matrix and % Correct
- Omission and Commission Errors
- Computation of Kappa Statistic
Plates 1-4 show selected screenshots of some modules of the software.
