Ravi Chityala gave this talk at All Things Python meetup held on November 4th 2015 in Sunnyvale. In this talk, Ravi Chityala introduced image processing using Python with some simple examples. The viewers will learn the basic image processing pipeline, image processing operations such as filter, segmentation, morphology etc.

Hello Sir.

import math, numpy
import scipy.misc
from scipy.misc.pilutil import Image

# opening the image and converting it to grayscale

im =

# im is converted to an ndarray

im1 = scipy.misc.fromimage(im)

b = im1.max()
a = im1.min()
print(a, b)

#%% This is a cell separator!

# converting im1 to float

c = im1.astype(float)

#%%
# contrast stretching transformation

im2 = 255*(c-a)/(b-a)

# im2 is converted from an ndarray to an image

im3 = scipy.misc.toimage(im2)

# saving im3 as new file
