Dynamic heatmap visualization of feature extraction in deep learning.
Input: Grayscale intensity. White (255)
represents high activation.
Output: A dynamic heatmap.
Green indicates
high positive values,
Red indicates
negative values, and
White/Gray is near
zero.
The colors highlight how the filter "responds" to patterns. An edge detector creates a bright spot (high value) exactly where a sharp color change occurs in the input.
