2Dinterpolation

2DInterpolation

Purpose

This program interpolates the value of the image stored in the file input_file at the point (u, v) where u, and v are any float numbers. The logical units are such that if an image is 65x65, then the logical units go from -32 to 32 in each direction. (0,0) is thus in the center of the image, (-32,-32) is the top-left corner and (32,32) is the bottom-right corner. If the image is of an even dimension, for instance 64x64, then the logical units go from -32 to 31, i.e., the logical center of the image lies on the center of a pixel.

Usage

$ 2Dinterpolation ...

Parameters Values

• `` Input file
• `` In logical units, may be float
• `` In logical units, may be float
