Topic: Image enhancement in the spatial domain. (Chapter 3 of the text book) using
Matlab Image Processing Toolbox
Tasks:
1. Intensity transformation: Select a gray level transformation method (Gamma
correction, histogram equalization, etc.) and apply it to images. Discuss the
results.
2. Spatial Filtering:
a. Select a linear smoothing filter and apply it to a noisy image. Vary the
filter size (3 x 3, 5 x 5, etc.) and compare the results.
b. Select an edge extraction filter and apply it to both noisy and noise-free
image and discuss your results.
c. Select an image sharpening filter and apply it to different kind of
images and discuss your findings.
d. Apply a non-linear order-statistic filter (e.g. median filter) on the noisy
image in part (a) and compare the results.
Report must contain the following information:
a. A brief discussion of the concept.
b. Spatial filters and parameter (if any) used.
c. Results (figures, tables, etc.) and concluding remarks.
d. Matlab code with necessary comments.
Note: You need to know how to add noise of different types to a clean image.
