Witryna21 lut 2024 · The nominal range of an integer-class image is the maximum dynamic range allowed by the datatype (e.g. 0-255 for uint8). For floating-point classes, images are expected to be unit-scale (black is 0, white is 1). Most times when you're creating variables programmatically, they're floating-point (class 'double') Witryna3 lis 2024 · If the image is double, imshow () assumes the image will be in the range 0-1. Anything below 0 will show up as black. Anything more than 1, like 100 or 255, will show up as white. Your image was all more than 1 so that's why it showed up as all white.

If it's a color image though, that won't work, you'd have to case to uint8 to display or use im2double and, unfortunately, have to deal with altered intensity values. WitrynaAn indexed image can be logical, uint8, double, or single. An intensity image can be logical, uint8, double, single, int16, or uint16. The input image must be nonsparse. If your image is int16 or single, the CData in the resulting image object will be double. For all other classes, the CData matches the input image class..

WitrynaDisplay the filtered image using imshow with the default display range. For images of data type double, the default display range is [0, 1]. The image appears black and white because the filtered pixel values exceed the range [0, 1]. imshow (edgeG) Display the filtered image and scale the display range to the pixel values in the image.
