Function Documentation

int imgMatch	(	IMG *	img1,
		IMG *	img2,
		float	accuracy
	)

Checks if two IMG data contents are similar (header information, frame times, data dimensions, matrix contents inside specified accuracy).

Returns:: Returns 0 if match was found, and >0 if not.

Parameters:

img1	Pointer to the first IMG data
img2	Pointer to the second IMG data to be compared against the first one
accuracy	Pixel values must satisfy condition abs(x1-x2)/abs(mean(x1,x2))<=0.01. If you want exact match, set accuracy=0.0.

Here is the call graph for this function:

int imgMatchFrames	(	IMG *	img1,
		IMG *	img2
	)

Checks if the frame times of two IMG data do match: return Returns 0 if match was found, and >0 if they do not match.

int imgMatchHeader	(	IMG *	img1,
		IMG *	img2
	)

Checks if two image headers match.

Returns:: Returns 0 if headers match, 1 if headers do not match.

int imgMatchMatrix	(	IMG *	img1,
		IMG *	img2,
		double	accuracy
	)

Checks if two image matrixes match in the accuracy of argument "accuracy". (set e.g. accuracy=0.99 and you will get match if all matrix values satisfy abs(x1-x2)/abs(mean(x1,x2))<=0.01) If you want exact match, set accuracy=0.0.

Returns:: Returns 0 if matrixes match, 1 if matrixes do not match.

int imgMatchPlanes	(	IMG *	img1,
		IMG *	img2
	)

Checks if the planes of two IMG data do match: plane numbers.

Returns:: Returns 0 if match was found, and >0 if no match.

int imgMaxDifference	(	IMG *	img1,
		IMG *	img2,
		VOXEL_4D *	absdiff,
		float *	abs_max,
		VOXEL_4D *	reldiff,
		float *	rel_max
	)

Checks if pixel values in two image matrices are similar withing specified allowed absolute difference.

Returns:: Returns 0 if successful, and difference was found, -1 if no difference was found, and >0 in case of an error.

Parameters:

img1	Pointer to the first IMG
img2	Pointer to the second IMG, with the same dimensions as img1
absdiff	Voxel where absolute difference was found largest; enter NULL if not needed; returns [0,0,0,0] if no difference was found
abs_max	Pointer where max absolute difference is written; NULL if not needed
reldiff	Voxel where relational difference was found largest; enter NULL if not needed; returns [0,0,0,0] if no difference was found
rel_max	Pointer where max relational difference is written; NULL if not needed
