imshowI

imshowI is a function used in image processing libraries to display image data with explicit control over the intensity scale. The name indicates an interface designed to visualize image values by mapping their intensities to displayable colors or grayscale output.

Purpose: It extends standard display functions by allowing the user to specify the minimum and maximum intensity values that correspond to the display range. This aids visualization of data with unusual or wide-ranging value ranges, floating point data, or high dynamic range imagery.

Features: imshowI typically supports both single-channel grayscale and multi-channel data, accepts a configurable colormap, and applies optional gamma correction. It may handle data types such as 8-bit, 16-bit, and floating point arrays, and can preserve or ignore an alpha channel as needed.

Usage: A typical call might resemble imshowI(image, Imin=0, Imax=1, cmap='viridis', gamma=1.0). The function usually returns a handle for further interaction or annotation. Some implementations offer interactive controls to adjust Imin and Imax at runtime.

Notes: While imshow is widely available in many toolkits, imshowI is a specialized variation not universally standardized. Its behavior depends on the host library, including how it handles clipping, normalization, and memory management.
