Automatic colorization of gray-scale images using color palette.
A simple algorithm is employed.
The speed of the algorithm and the quality of the result colored image depends on the correct selection of the color palette image. The smaller the size of the palette, the faster the algorithm.
Wavelet based square image enlargemant (zooming in).
Zooming is performed by employing the idwt2() MATLAB function, with a wavelet
family determined by 'wname'.
The size and quality of the final zoomed image 'output_image' depends on
CCDF Complementary Cumulative Distribution Function of an array of numbers. Y = CCDF(X,STEP) returns an array of values of the complementary cumulative distribution function for the N-Dimensional array X, calculated for
each element of the...
There are many techniques used to deal with the problem of high PAPR in OFDM systems. An effective one is the Partial Transmit Sequence. It is simulated for QPSK modulated 64-subband OFDM system.
Moreover, a .mat file of 100000 such OFDM...
Two functions to find the value and position of the first min and max in a 2D matrix
ofdm symbol generation of QPSK subsymbols for testing PAPR reduction algorithms.
