I have a code like below. I want convert the image from picture-box to apply median-filter by EmguCV. And the problem is that the "out of memory" problem occurs even though I dispose the image. After I click many button handler, the first line occurs show the problem. Please help me!

Bitmap bm1 = new Bitmap(imgBox.Image); //Out of memory
Image<Gray, byte> EmguImage1 = new Image<Gray, byte>(bm1);
EmguImage = EmguImage1.SmoothMedian(1);
imgBox.Image.Dispose();
imgBox.Image = EmguImage1.Bitmap;
bm1.Dispose();
EmguImage1.Dispose();

In which line does the OutOfMemoryException occurs? – scher Aug 02 '17 at 06:14
@scher I edited it! The exception occurs in the first line – Huu Tin Aug 02 '17 at 08:07
So disposing takes no effect, when the exception occures prior to it. How big is the Image? – scher Aug 02 '17 at 09:00
@scher the image is from 13 to 16Mb – Huu Tin Aug 02 '17 at 09:17
If the image is jpeg or png or any other compressed format it gets uncompressed while loading it in the `Bitmap`. So the size might by much larger then then the compressed. – scher Aug 02 '17 at 10:09
@scher I know that but the problem is that whether the way I dispose the image correctly or not. – Huu Tin Aug 03 '17 at 01:54
Do you get it the first time when you call this code, or later – scher Aug 03 '17 at 04:40
No, I get it to many time later. 5 or 6 first times, I don't get it but It occurs when more than 6 times. – Huu Tin Aug 03 '17 at 07:00
