hello
if anyone can help me in specify image bands using matlab, plzzz replay
as soon as possible
this is my image registration algorithm in which step 8 is related to
image band
1. Apply FFT to images I1 and I2 F1(x, h) and F2(x, h);
2. Compute the absolute values of F1(x, h) and F2(x, h);
3. Apply a high pass filter to the absolute values to remove low
frequency noise;
4. Transform the resulting values from rectangular coordinates to
log-polar coordinates;
5. Apply the FFT to log-polar images I1 and I2 Flp1(x, h) and
Flp2(x, h);
6. Compute the ratio R1 of Flp1(x, h) and Flp2(x, h) using equation
(2);
7. Compute the inverse FFT IR1 of the ratio R1;
8. Find the location of the maximum of abs(IR1) and obtain the
values of scale, and rotation angle ;
maxn = MAX(abs(inv-R), position)
scale = b^(position MOD rows)
angle = 180.0 * (position / rows) / cols
position is : the band position (is a long integer with a value from
zero to number-of-bands minus one) of the image.
how can i specify this position in matlab ??
thanxxxxxx alot
