Grayscale to Pseudocolor Image Conversion

This document explores methods for converting grayscale images to pseudocolor images. The transformation from grayscale to pseudocolor represents a crucial step in image processing that significantly improves visualization effectiveness. We can implement this conversion using MATLAB through a programmable approach that applies color mapping techniques. The core algorithm involves mapping intensity values from the grayscale image to specific color triplets in RGB space using predefined colormaps or custom color transformations. By modifying parameters like colormap selection, contrast enhancement values, and intensity thresholds in the code, users can create more sophisticated pseudocolor images. The conversion process requires careful handling of different color channels through matrix operations and indexing techniques to achieve desired color representations in the final output. While this process demands some technical expertise in color space transformations and image matrix manipulation, mastering these techniques enables better image processing capabilities and superior visualization outcomes. Key MATLAB functions involved include ind2rgb for index-based color mapping, colormap manipulation functions, and intensity scaling operations for optimal color distribution.
