Evaluate MTF for current object settings
vcimageISOMTF;
The function creates a slanted bar scene. Then, it uses the existing
(selected) optics, sensor and image processing parameters to compute
the vcimage.
The routine invokes the ISO 12233 routine from within the vcimage
window to produce the MTF figure. The frequency and mtf data can be
retrieved from the figure via
data = get(gcf,'userdata');
Comment (and to check)
Frequency is specified in cycles/mm at the sensor surface. This can be
converted into cycles per degree by calculating the sensor field of view and sensor
size (horizontal). This gives deg/mm.
deg = sensorGet(isa,'fov')
mm = sensorGet(isa,'width')*1000;
freqInCpd = data.freq*(mm/deg);
plot(freqInCpd,data.mtf)
