Hallo ich möchte ein Bild (*.png; Bmp) mit einer Größe von > 8MB verwenden. Dieses Bild wurde von einer GigE Kamera aufgenommnen und dient zur Partikelbestimmung. Es wird eine Blobanalyse zur Sauberkeitsanalyse verwendet. Wie kann ich in MAtlab mit großen Bildern ohne Datenkomprimierung umgehen?
A picture, use a size of> 8MB (* png bmp.). Made this image of a GigE camera. There is a blob analysis used for cleanliness analysis. How can I deal with large images in matlab without data compression?

8 MB is not large. There is not problem to access such arrays. If you observe any problems, describe them with details.

The only problem I can possibly think of is that the frame rate is not as high as you'd like. Is that it? Because, like Jan said, 8 MB is not large at all. Even a garden variety 18 megapixel DSLR camera is 54 MB uncompressed so 8 is way, way below an ordinary digital image these days. And MATLAB can handle them quite well, other than of course not being able to process as fast as you'd like.
