Zinnia 是一个简单、可定制和可移植的手写识别系统，基于 Support Vector Machines (SVM) 算法。SVM算法简介。
实例代码：
#include <stdio.h> #include "zinnia.h" int main(int argc, char **argv) { size_t i; zinnia_recognizer_t *recognizer; zinnia_character_t *character; zinnia_result_t *result; recognizer = zinnia_recognizer_new(); if (!zinnia_recognizer_open(recognizer, "/usr/local/lib/zinnia/model/tomoe/handwriting-ja.model")) { fprintf(stderr, "ERROR: %s\n", zinnia_recognizer_strerror(recognizer)); return -1; } zinnia_character_t *character = zinnia_character_new(); zinnia_character_clear(character); zinnia_character_set_width(character, 300); zinnia_character_set_height(character, 300); zinnia_character_add(character, 0, 51, 29); zinnia_character_add(character, 0, 117, 41); zinnia_character_add(character, 1, 99, 65); zinnia_character_add(character, 1, 219, 77); zinnia_character_add(character, 2, 27, 131); zinnia_character_add(character, 2, 261, 131); zinnia_character_add(character, 3, 129, 17); zinnia_character_add(character, 3, 57, 203); zinnia_character_add(character, 4, 111, 71); zinnia_character_add(character, 4, 219, 173); zinnia_character_add(character, 5, 81, 161); zinnia_character_add(character, 5, 93, 281); zinnia_character_add(character, 6, 99, 167); zinnia_character_add(character, 6, 207, 167); zinnia_character_add(character, 6, 189, 245); zinnia_character_add(character, 7, 99, 227); zinnia_character_add(character, 7, 189, 227); zinnia_character_add(character, 8, 111, 257); zinnia_character_add(character, 8, 189, 245); result = zinnia_recognizer_classify(recognizer, character, 10); if (result == NULL) { fprintf(stderr, "%s\n", zinnia_recognizer_strerror(recognizer)); return -1; } for (i = 0; i < zinnia_result_size(result); ++i) { fprintf(stdout, "%s\t%f\n", zinnia_result_value(result, i), zinnia_result_score(result, i)); } zinnia_result_destroy(result); zinnia_character_destroy(character); zinnia_recognizer_destroy(recognizer); return 0; }
