+function new_image = IDCT(image)
+// Compute inverse Discrete Transform of image
+//
+// Calling Sequence
+// newimage = IDCT(image)
+//
+// Parameters
+// image : floating-point image
+// newimage : IDCT of the input image
+//
+// Description
+// The IDCT function computes the inverse cosine transform of a floating-point image with even number of rows and columns.
+//
+// Examples
+// I = imread('cameraman.tif')
+// I = double(I)
+// J = IDCT(I)
+// imshow(J)
+//
+// Authors
+// Suraj Prakash
