    <p>Hi,</p> <p>I have a problem to get a reasonable result from classification. When I make classification using pixel/based class like maximum likelihood, minimum distance etc. everzthing is ok. But when i what to perfome Neural net or SVM classification i recive white raster. I tried with menz diffrent parameters and nothing help.The data which i want to classify are raster dataset from arcgis. I make in in envi 32bit mode because it is compatible with arcGIS, but i also tried to do it with tiff image but it also doent work. Also the data are not readable in envi classic, i see onlz white sheet. Is anybody hier who could help me or have some ideas where the problem is? Thank you very much in advance!</p> <p>Regards </p> <p><img alt="" /></p> <h3>&nbsp;</h3>

    If the image is all white, it sounds like a display stretch problem. If you calculate statistics on your image, what are the range of values?
