Which is the false statement regarding Fourier transform?
Fourier transform helps in image enhancement
Any function that periodically repeats itself can be expressed as the sum
of sines and/or cosines of different frequencies, each multiplied by a
different coefficient
A function, expressed in Fourier transform, can be reconstructed
(recovered) completely via an inverse process, with loss of information.
The practical application of Fourier transform started late 1950's with
advent of digital computation.
A filter returns 50th percentile of a ranked set of values.
Midpoint Mean
Median Min and Max
When a closing is persormed on an equilateral triangle of each side 3 cm
using a structuring element which is right angle triangle with base and height
the change in the area of result will be
Area remains same but shape
changes
Area and shape remain
same
Area increases Area decreases
