/*************************************************************************** * tsvqlib.h * written by: Stephanie Wojtkowski * * Description:  A library that provides tree-structured VQ tools for  * performing the Wei-Levoy texture synthesis method. * ------------------------------------------------------------------------- * BuildTree(image, rows, cols, maxdepth) * Input:      image - the input image from which a new texture will be  *                     generated *             rows - the number of rows in the image *             cols - the number of columns in the image *             maxdepth - the maximum depth of the VQ tree * * Description: This function creates a vector-quantized tree of pixel * neighborhoods based on the input image. * ------------------------------------------------------------------------- * FindMatch(point) * Inputs:     point - the pixel neighborhood in the target image that is  * being processed * Output: a pixel value containg the best match from the tree * * Description: Given a pixel neighborhood, FindMatch traverses the tree to  * find the best match for that neighborhood ***************************************************************************/#define TSVQLIB_H#ifdef TSVQLIB_H#include <stdio.h>#include <stdlib.h>#include <math.h>#include <time.h>#include "ppmIO.h"#define NRAD 1    //Neighborhood radius//The amount of space necessary to store a pixel and its neighborhood#define SIZE (2*NRAD+1)*NRAD + NRAD + 1typedef Pixel Vector[SIZE];typedef struct node {  Vector data;    //The neighborhood plus the neighborhood origin  struct node *left;  struct node *right;} node;node *root;void BuildTree(Pixel *image, int rows, int cols, int depth);Pixel FindMatch(Vector point);#endif
