SYLLABUS

Semester V - Paper II - Digital Image Processing

Duration: 3 hrs
Maximum Marks: 100
Credits: 4

UNIT I

Image representation and Preliminaries - Image and Digital images: Different types of images and acquistion (like real images, aerial images, etc.), simple image model, sampling and reconstruction - uniform sampling and quantisation - Information on image formats - Graphic representation on theory, RLE, LZW, DCT, BIVIP, TIFF, GIF, PIX, JPEG etc.

UNIT II

Digital Analysis - image rectification and restoration: Radiometric, atmospheric and geometric corrections, correction in the spatial spectrum of the images. image enhacement - Contrast manipulation, Gray-level thresholding, level slicing, and contrast stretching, Spatial feature manipulation - Spatial filtering, edge enhacement and fourier analysis.

UNIT III

Mult-image manipulation - Multispectral band ratio and differencing, principal components, canonical components, vegetation components, and intensity-hue-saturation (HIS) colour space transformation.

UNIT IV

Image classification, Supervised classification - the classification stage, minimum distance to mean classifier, parallelepiped classifier, Gaussian maximum likelihood classifier and the training stage.

UNIT V

Unsupervised classification - output stage, graphic products, tabular data, post classification smoothing, Classification Accuracy Assessment, Data merging - multitemporal data merging, change detection procedures, multisensor image merging, merging of image data with ancillary information.
