EXPERIMENT NO. 3
TITLE: Contrast stretching and image negative
AIM: To perform contrast stretching of the given image using point processing techniques
and to find negative of the image.
THEORY: In this experiment we are going to study few examples of ima
EXPERIMENT NO. 11
TITLE: EDGE DETECTION
AIM: To perform edge detection using Sobel, Laplace.
THEORY:
Edges characterise object boundaries and therefore useful for segmentation and
identification of objects in the scenes. Edge is the boundary between two r

EXPERIMENT NO. 4
TITLE: HISTOGRAM EQUALIZATION
AIM: To find the histogram of an image and perform histogram equalization.
THEORY:
HISTOGRAM EQUALIZATION:
The histogram of a digital image is a discrete function
h(rk) = nk / n
where rk is the kth gray level
