Я пытаюсь выбрать целые числа из массива OpenCvSharp.Point.
Dim hull() As Integer = Cv2.ConvexHullIndices(origPoints.Skip(48)).Select(i >= i + 48)
Эта строка завершается ошибкой, компилятор сообщает мне «Ошибка перегрузки, потому что для этих типов аргументов нет [Select]».
Как правильно это сделать?
origPoints объявлен так:
Dim origPoints() As OpenCvSharp.Point
ConverHullIndices объявлен так:
Public Shared Function ConvexHullIndices(points As IEnumerable(Of Point), Optional clockwise As Boolean = False) As Integer()
OpenCvSharp.Point объявлен так:
