Issue with Intensity Range in ITK-SNAP Toolbox #152

Open YaoHuanyu opened 11 hours ago

YaoHuanyu commented 11 hours ago

Description: When using the ITK-SNAP Toolbox, an issue was found with the intensity range of the image. There are some pixels in the image with intensity values greater than the maximum intensity value displayed by the tool. These pixels exceeding the maximum intensity value are displayed as black, affecting the correct visualization and analysis of the image.

Specifically: In the main interface of the tool, the Cursor Inspector shows Cursor position (xy,z): 281 363 197, Intensity under cursor: Intensity 3068. However, the image intensity range shows Reorient min: -1024 max: 2998 int16, but there are currently pixels in the image with intensities greater than the maximum value of 2998 yet displayed as black.

Expected: Hope the development team can check and fix the issue with the image intensity range display to ensure that pixels exceeding the maximum intensity value can be displayed correctly or provide a reasonable processing method for better image analysis and visualization.
