我在java中使用opencv。我正面臨這個奇怪的問題,在我做了dilate
函數後,我的圖片改變了它的大小。在documentation明確說:在java opencv中使用擴展名時更改大小
dst - 輸出圖像的大小和類型與src相同。
我的代碼是:
Log.d(TAG, "dilate size1 " + dilate.size().height + " " + dilate.size().width);
Imgproc.GaussianBlur(warpg, smooth, new Size(3, 3), 3);
Log.d(TAG, "smooth size1 " + smooth.size().height + " " + smooth.size().width);
Imgproc.adaptiveThreshold(smooth, thresh, 255, 0, 1, 5, 2);
Log.d(TAG, "thresh size1 " + thresh.size().height + " " + thresh.size().width);
kernel = Imgproc.getStructuringElement(Imgproc.MORPH_CROSS, new Size(3, 3));
Imgproc.erode(thresh, erode, kernel, new Point(-1, -1), 1);
Log.d(TAG, "erode size1 " + erode.size().height + " " + erode.size().width);
Imgproc.dilate(erode, dilate, kernel, new Point(-1, -1), 1);
Imgproc.findContours(thresh, contours, hierarchy,
Imgproc.RETR_TREE, Imgproc.CHAIN_APPROX_SIMPLE);
Log.d(TAG, "dilate size2 " + dilate.size().height + " " + dilate.size().width);
輸出是:
dilate size1 450.0 450.0
smooth size1 450.0 450.0
thresh size1 450.0 450.0
erode size1 450.0 450.0
dilate size2 1.0 313.0
任何想法?
