##Fled

A program used to demonstrate finding the morse code letter that a blinking light is emitting

####Usage

fled <duration> <resolution x> <resolution y> <patch_height> <patch_width> <channel>

<duration> how long the camera will record the light

<resolution x> resizes the images to the number of pixels in the x direction setting this value to -1 will make the program use the original size

<resolution x> see <resolution y>

<patch_height> the height of the convolution kernel in pixels

<patch_width> the width of the convolution kernel in pixels

<channel> the channel to be analysed, can be one of * H — Hue channel of the HLS color space * L — Light channel of the HLS color space * S — Saturation channel of the HLS color space * B — Blue channel of the BGR color space * G — Green channel of the BGR color space * R — Red channel of the BGR color space * GREY — A greyscale version of the image

if a value is input that is not included in the list above the program will default to a greyscale image.

To start recording simply press enter, when the recording is done the program will show you the location of the light and its morse code value. If you want to exit the program go back to the webcam window and press escape.
