The Window Design Method
The basic IDEA behind the design of linear-phase FIR filters using the window
method is to choose a proper IDEAl frequency-selective filter [which always has
a noncausal, infinite duration impulse response] and then truncate its impulse
response hd[n] to obtain a linear-phase and causal FIR filter h[n]. To truncate the
impulse response of the IDEAl filter a time window w[n] is used. Available windows
in Matlab are rectangular [or boxcar in Matlab], bartlett, hamming, hanning
Using the IDEA from Seam Carving for Content-Aware Image Resizing, the codes enables a selected image to resize without having distortion of important object in the image file.
