Ошибка C3861: «cvPyrSegmentation»: идентификатор не найден

Не могли бы вы помочь мне ??? Получение ошибки при выполнении кода ниже. Я новичок в использовании OpenCV. Мой учитель — мистер Гугл, а вы, ребята, являетесь экспертом в этой области.

IntelliSense: идентификатор «cvPyrSegmentation» не определен
