Creates CvMatND header only

Decrements CvMat data reference counter and deallocates the data if it reaches 0 */

The function add to tree the last retrieved/substituted contour, releases temp_storage, restores state of dst_storage (if needed), and returns

Returns a number of array dimensions

Connects the two given vertices if they were not connected before, otherwise it returns the existing edge */

Increments CvMat data reference counter */

initalize IplImage header, allocated by the user

constructs sequence from array without copying any data. the resultant sequence can't grow above its initial size */

returns zero value if iteration is finished, non-zero otherwise

Releases CvMatND */

pops the last element out of the sequence */

removes element from the sequence */

adds new element to the set */

adjusts <delta_elems> field of sequence. It determines how much the sequence grows if there are no free space inside the sequence buffers */

dst(mask) = src(mask) - value = src(mask) + (-value) */
