How to obtain image matching position and its subpixel accuracy?
Hello All, Please could you explain how can I find the image matching positions once I know matching values for all pixels in the image and how to get the subpixel accuracy. I know I might be in the wrong place but here there are a lot of image processing/computer vision experts. I am now working on my midterm fo... 29 Apr 2010 06:45

How can I plot two different y-axis (right and left) with a reverse-logarithmic x-axis?
Let us look at this example: x = 0:0.01:20; y1 = 200*exp(-0.05*x).*sin(x); y2 = 0.8*exp(-0.5*x).*sin(10*x); [AX,H1,H2] = plotyy(x,y1,x,y2,'plot'); Now how can one reverse x-axis and at the same time in logarithmic scale? Even using (Tools>Edit plot>Property edittor>Axis) in Figure window is not giving contro... 29 Apr 2010 06:45

bode of pade approximant
Hey, I need to add a time delay to a system sys. I'm using the function pade to create the time delay, eg, Td = 1e-3; N = 2; [num,den] = pade(Td,N); delay = tf(num,den); bode(delay); The strange thing now is that the magnitude of the bode is correct (continuously a gain of 1). But the phase is doing wei... 29 Apr 2010 04:35
