Почему я получаю OutOfMemoryError? Я попробовал его с другим дедектором, и там он работает ?! Я также рассмотрел некоторые другие вопросы для ответа, и я нашел одно решение, и я с ним работал, но он тоже не работал. Это мой первый опыт работы с Openimaj.OutOfMemoryError после Facededetion
Exception in thread "Thread-4" java.lang.OutOfMemoryError: Java heap space
