# Composition Examples
|
|
Keeping everything the same, but changing the composition to demonstrate visual differences.
|
|
|
|
## Understanding compostion modes
|
|
These control how the saliency map is composited back onto the original image. This is where the artistic intent lives.
|
|
isolation — The default and most conceptually pointed for your project. Salient regions show in full color using the chosen colormap; everything else is converted to greyscale. The effect: the machine's gaze burns in color while everything it ignores fades to grey. Very direct visual commentary on algorithmic attention.
|
|
overlay — Classic heatmap blend. The colormap is alpha-composited over the original at the intensity level. Familiar, readable, less subversive.
|
|
spotlight — The salient regions are bright, everything else darkens dramatically. Feels like a searchlight or surveillance camera — forensic, clinical.
|
|
ghost — The original image fades to 25% opacity and the saliency map glows over it. The subject becomes spectral, haunted by its own classification. Good for an uncanny effect.
|
|
invert — Shows what the algorithm ignores instead of what it sees. The saliency map is flipped before compositing. Conceptually this is the most subversive mode — it visualizes the blind spots, the parts of a face that are invisible to the machine.
|
|
cutout — Hard binary mask. Pixels above the threshold value show the original image; everything below shows a dim version of the heatmap. Creates a stark, graphic effect — the subject literally cut out by the algorithm's attention boundary.
|
|
multiply — Photoshop-style multiply blend. Attention dims non-salient areas. Produces a dark, moody result where ignored regions sink into shadow.
|
|
screen — Photoshop-style screen blend. Attention brightens salient regions. Lighter and more luminous than multiply — glowing rather than shadowed.
|
|
triptych — Outputs three panels side by side: original | saliency map alone | composite. Designed for gallery or exhibition display — shows the full chain of the visualization in one image.
|
|
mask_only — Just the colored saliency map with no original image. Pure algorithmic output, no human context.
