| img_id visual_database::add_image | ( | IplImage * | im | ) |

| visual_object * visual_database::create_object | ( | const char * | comment = 0, |

Creates a new visual_object.
The object is in the database, but not in the index. No query will find it until add_to_index() is called.

| IplImage * visual_database::get_image | ( | img_id | im_id | ) |
Fetches an image from the database.
It also caches the image, so that subsequent fetching of the same image is very fast.

| sqlite3* visual_database::get_sqlite3_db | ( | ) | [inline] |
| bool visual_database::open | ( | const char * | fn | ) |
Reads or create a sqlite3 database file for visual objects.
Calling this method is required. If the file does not exists, it is created. If the file exists, the method indexes every entry in it. After a successfull call to open(), query_frame or create_incremental_query() are ready to be called.
