Ground Truth Files Readme
-------------------------

The format for all the files are as follows:
-------------------------

Note: POSITION(X,Y) where X is x-pos and Y is y-pos, from top left corner.

<startOfFile>
# width height datatype(name)
WIDTH HEIGHT DATATYPE<newline>
POSITION(0,0) POSITION(1,0) POSITION(2,0) ... POSITION(WIDTH-1,HEIGHT-1) 
<endOfFile>

The data after the header is in binary data format.
Please use the provided imageIO to read / write images.

-------------------------
WIDTH         = integer value
HEIGHT        = integer value
POSITION(X,Y) = float value


Specifics for files:

flowX_###	Flow in the X direction in pixels from previous frame to current frame. 
                -ve = to the left. +ve = to the right.
flowY_###	Flow in the Y direction in pixels from previous frame to current frame. 
                -ve = to the top. +ve = to the bottom.

Example: 	The (u,v) motion vector generated using the files 
		flowX_00n.raw and flowY_00n.raw at POSITION(Xn,Yn), 
		contains the motion information of a pixel on frame
		n-1 at POSITION(X,Y), such that after the motion 
		defined by (u,v), it will end up at POSITION(Xn,Yn)
		on frame n.

		POSITION(X,Y) can be recovered using the following:

		POSITION(X,Y) = POSITION(Xn,Yn) - (u,v)


flowD_###	Change in disparity from previous to current image.
                -ve = moving away from camera, +ve = moving toward camera.
                (See Wedel et al., ECCV 2008 for explination of scene flow)
disp_###	Disparity from left image to right image.
                Value of -1.f indicates occlusion.
