I've written the following code to calculate the Mean Values of x, y & z.
***************************************************************
for i=2:size(A) % A = column of input data
x(i) = % formula
y(i) = % formula
z(i) = % formula
end
Mean_x=mean(x); % mean...
I desparately need Matlab codes for noise & shading correction of 16bit tiff file captured with an experimental digital camera. I have three images: One is the noisy original captured image, one is the dark noise image (black) taken with the camera shutter closed and the other is the white...
The captured image from a camera is 12 bit but saved in the computer as 16 bit tiff image with postfix '0' bits. During capture, the pixel values don't exceed 4095 as should be with 12 bit images. But after saving the image and openning in Matlab, the "imview(image)" command shows 16 bit values...
I'm capturing raw images from an experimental CMOS digital camera. However, this camera doesn't have RGB masks on the CMOS. Instead, the CMOS is monochrome. An instrument with camera lens is fitted infront of the CMOS that has four apertures so that the input image on the CMOS screen is divided...
I need to drive a miniature relay with maximum coil voltage of 5 V and minimum coil current of 200 mA by a timer circuit. The circuit need to turn it ON & OFF every 8-10 minutes. Please help! Thanks in advance!
I have a multiplexer circuit that I built to control the main circuit but it makes the circuit very large because of large numbers of dicreet ICs. I want to do the timing by EEPROM but I don't know how to program one and what do I need other than the EEPROM IC. Please advise!
It's a sensing system for patients that would lit an LED when there is 1. At present it's built as a compact system as an experiment. I would like to separate the indicator part from the main circuit so that the indicator can be placed somewhere else, for example nurse stations. I've asked for...
I have designed a sensor in which light from LED (main) is detected by a Photodiode (PD). The received signal is then filtered and is made to flash an LED (indicator) when the received signal goes above a threshold voltage. The main LED is driven by a 500 hz squre wave signal. This whole thing...
I need to transmit a 500 hz square wave without interference upto a distance of 50~60 meters that has to be picked up by the receiver at the other end. For this I need to have a transmitter-receiver circuit. Could someone plz help with a schematic! Thanks in advance!
I need to build a circuit using Photodiode that will receive light from ultraviolet incandescent lamp (50/60 Hz line voltage), amplify and filter the signal and give dc output depending on the amplitude of the light. I'll be using an ultraviolet Photodiode for this purpose. Any help would be...
