Photo Decode / 解图

一张图，解出另一种视觉。

Photo Decode is an AI Skill for visual analysis and structural image decoding. It analyzes a source image, reconstructs its visual logic into a new source-adaptive flat composition, derives a color palette, and reveals key visual elements.

As a Codex Skill, it supports image analysis and photo analysis across photographs, paintings, portraits, landscapes, architecture, products, animals and action scenes. Its visual reconstruction and image generation workflow is source-adaptive, not a style filter.

Its signature pipeline is:

analyze structure → choose what matters → remove background → compress relations → reconstruct a source-adaptive flat visual → derive palette → reconstruct key visual grammar

Why V2 exists

V1 exposed two portability failures in clean sessions:

1. unrelated inputs could collapse into one engraving/printmaking look;
2. KEY ELEMENTS could degrade into crops/cutouts instead of meaningful visual abstractions.

V2 removes both shortcuts from the architecture itself.

Fixed five-block board

1. ORIGINAL SOURCE
2. REINTERPRETED VISUAL (FLAT)
3. IMAGE ESSENCE
4. COLOR PALETTE
5. KEY ELEMENTS

What “flat” means

Flat means structural depth and information are compressed. It does not mean every source becomes a minimal vector drawing.

An ornate temple may stay richly articulated. A portrait may become restrained. A city may preserve dense roofline rhythm. A sports image may preserve collision/action geometry. The visual language follows the source.

KEY ELEMENTS in V2

KEY ELEMENTS are independently reconstructed visual grammar units. They are not crops, screenshots, masks or generic icons.

They answer: what forms, relations, rhythms, junctions, gestures or motifs make this image visually itself?

Cold-start reliability

V2 includes a mandatory cold-start test. A release fails if a clean new session:

• applies one fixed art style across unrelated inputs; or
• turns KEY ELEMENTS into crops/icons.

Golden behavior reference

See assets/golden-behavior-reference.png. It demonstrates behavioral diversity, not one style to imitate.
