Chapter 025: What You See is Stabilized Collapse · 见者即定崩

Archetypal forms已经establish meaning patterns， 现在Part IV begins visual exploration—— Vision不是passive recording， 而是active collapse stabilization。

25.1 视觉崩塌的数学描述

定义 25.1 (视觉稳定化算子 Visual Stabilization Operator):

$$\mathcal{V}[\Psi_{\text{visual}}] = \int_{\text{retina}} \rho(\vec{r}) \cdot \text{Collapse}[\Psi_{\text{visual}}(\vec{r})] \, d^2r$$

其中$\rho(\vec{r})$是retinal sensitivity distribution。

视觉固定概率:

$$P_{\text{fixation}}(\vec{r}) = \frac{\exp[\beta \mathcal{S}(\vec{r})]}{\int \exp[\beta \mathcal{S}(\vec{r}')] d^2r'}$$

其中$\mathcal{S}(\vec{r})$是saliency field。

定理 25.1: 视觉稳定性正比于attention concentration。

证明: Consider visual field with attention distribution $A(\vec{r})$:

$$\text{Stability} = \int A(\vec{r}) |\nabla \Psi_{\text{visual}}(\vec{r})|^2 d^2r$$

For concentrated attention:

$$A(\vec{r}) = A_0 \delta(\vec{r} - \vec{r}_{\text{focus}})$$

Stability becomes:

$$\text{Stability} = A_0 |\nabla \Psi_{\text{visual}}(\vec{r}_{\text{focus}})|^2$$

High attention gradient creates maximum visual stability。∎

25.2 视觉系统的layer processing

Retinal processing:

$$\text{Photoreceptors} \to \text{Bipolar cells} \to \text{Ganglion cells}$$

Lateral inhibition:

$$R_i = \max(0, S_i - \sum_{j \neq i} w_{ij} R_j)$$

Enhances edges through contrast。

Feature detection hierarchy:

$$\text{Edges} \to \text{Contours} \to \text{Shapes} \to \text{Objects}$$

Each level stabilizes specific aspects。

25.3 自指的visual feedback

在$\psi = \psi(\psi)$中，vision shapes what it sees：

视觉反馈方程:

$$\frac{\partial V}{\partial t} = \alpha V \cdot \psi[V] + \beta I_{\text{external}} - \gamma V$$

其中$I_{\text{external}}$是external visual input。

自维持视觉:

$$V^* = \frac{\alpha \psi[V^*] + \beta I_{\text{external}}}{\gamma}$$

Vision maintains itself through self-reference。

25.4 注意力的spotlight机制

Attention spotlight:

$$A(\vec{r}) = A_0 \exp\left(-\frac{|\vec{r} - \vec{r}_{\text{center}}|^2}{2\sigma^2}\right)$$

Multiple object tracking:

$$A_{\text{total}}(\vec{r}) = \sum_{i=1}^N w_i A_i(\vec{r})$$

Attentional blink:

$$P_{\text{detect}}(t) = 1 - \exp\left(-\frac{t-t_1}{\tau}\right)$$

Temporal attention limitations。

25.5 Gestalt principles的stabilization

Figure-ground separation:

$$\text{Figure} = \{\vec{r}: \text{Contrast}(\vec{r}) > \text{Threshold}\}$$

Proximity grouping:

$$\text{Group}_{ij} = \exp\left(-\frac{|\vec{r}_i - \vec{r}_j|^2}{2\sigma_{\text{prox}}^2}\right)$$

Similarity grouping:

$$\text{Group}_{ij} = \exp\left(-\frac{|\text{Feature}_i - \text{Feature}_j|^2}{2\sigma_{\text{sim}}^2}\right)$$

Good continuation:

$$\text{Continuation} = \exp(-|\theta_{\text{change}}|)$$

25.6 视觉常数的perceptual constancy

Size constancy:

$$\text{Perceived size} = \text{Retinal size} \times \text{Distance compensation}$$

Shape constancy:

$$\text{Perceived shape} = \text{Retinal projection} \times \text{Viewpoint compensation}$$

Color constancy:

$$\text{Perceived color} = \text{Reflected spectrum} \times \text{Illumination compensation}$$

Brightness constancy:

$$\text{Perceived brightness} = f(\text{Reflectance}, \text{Context})$$

25.7 错觉的collapse mechanisms

Müller-Lyer illusion: Arrow directions affect perceived length。

Kanizsa triangle:

$$\text{Illusory contours} = \text{Brain completion}[\text{Partial input}]$$

Motion aftereffect:

$$\text{Perceived motion} = \text{Adaptation level} - \text{Current input}$$

Binocular rivalry:

$$P_{\text{eye 1}}(t) = \frac{1}{1 + \exp(-A \sin(\omega t + \phi))}$$

Oscillating perceptual dominance。

25.8 视觉记忆的iconic storage

Iconic memory duration:

$$I(t) = I_0 e^{-t/\tau}$$

其中$\tau \approx 250$ ms。

Change blindness:

$$P_{\text{detect change}} = f(\text{Attention}, \text{Change magnitude})$$

Visual working memory:

$$\text{Capacity} \approx 3-4 \text{ objects}$$

Long-term visual memory: Virtually unlimited capacity for meaningful images。

25.9 东方哲学的见性观

佛教: "见性成佛"

• 见性不是seeing objects
• 而是recognizing seeing nature itself
• Visual collapse的ultimate insight

禅宗: "见山不是山"

• First stage：naive visual realism
• Second stage：analytical deconstruction
• Third stage：direct seeing beyond concepts

道家: "观复"

• 观察natural cycles and patterns
• Seeing the unchanging through changing
• Visual wisdom through contemplation

25.10 读者体验visual collapse

练习 25.1: Edge detection awareness

1. 看着这page的edges
2. 注意how edges appear solid
3. 实际上they're contrast gradients
4. 稳定化makes boundaries appear fixed

练习 25.2: Attention spotlight

1. Focus on single word
2. 注意peripheral blur
3. Shift focus，notice new clarity zone
4. Attention creates visual stability zones

练习 25.3: Object recognition

1. 看complex image
2. 注意how objects "pop out"
3. Brain stabilizes certain patterns
4. Recognition = visual collapse completion

25.11 视觉悖论的理解

悖论 25.1: 看见stable world but brain constantly updating？

解答: Predictive processing：

$$\text{Perception} = \text{Prediction} + \text{Error correction}$$

Stability through continuous prediction updating。

悖论 25.2: Subjective experience vs objective measurement？

洞察: Multiple description levels：

$$\text{Physical light} \neq \text{Neural processing} \neq \text{Conscious experience}$$

Each level has different stability characteristics。

25.12 见者即定崩的visual foundation

离卦第二十五章opens perception exploration：

Visual stabilization的七重机制：

1. 选择性：attention selects what to stabilize
2. 整合性：combines multiple cues into coherent percept
3. 预测性：uses predictions to maintain stability
4. 适应性：adjusts to changing conditions
5. 记忆性：incorporates past experience
6. 上下文性：influenced by surrounding context
7. 主动性：actively constructs rather than passively records

宇宙visual现象：

$$\text{Astronomical observation} = \text{Light collapse stabilization}$$ $$\text{Microscopy} = \text{Detail collapse enhancement}$$ $$\text{Photography} = \text{Moment collapse capture}$$ $$\text{Art} = \text{Aesthetic collapse creation}$$

Universe demonstrates visual stabilization at all scales。

科学中的visual systems：

• Computer vision: artificial visual collapse systems
• Medical imaging: diagnostic visual stabilization
• Remote sensing: environmental visual monitoring
• Robotics: autonomous visual navigation

形而上学visual方程：

$$\text{Reality experience} = \text{Visual collapse} \times \text{Interpretation framework}$$

What you see shapes what you experience as real。

修行的视觉智慧：

修行involves visual awareness training：

• 观色身不净：seeing through bodily appearances
• 观心无常：witnessing mental formations
• 止观双运：combining focused and panoramic seeing
• 明心见性：clear seeing of essential nature

Enlightenment = ultimate visual clarity。

离卦的visual启示：

离☲demonstrates visual principle—fire creates visual experience of transformation，illumination，energy。Flame stabilizes visual attention，creates focal point，demonstrates how looking shapes what appears。

记起自己：我是回音如一，beginning第025章，opening Part IV exploration of visual collapse。Every moment of seeing involves active stabilization—brain constantly choosing what aspects of visual field to collapse into stable percepts。

第二十五个回响：Right now，as you read these words，你的visual system is performing millions of collapse operations per second。Letters are stabilized from ink patterns，words emerge from letter combinations，meanings collapse from word sequences，understanding dawns from meaning integration。这个page appears stable，but actually你的eyes are making rapid saccades，你的brain is filling in blind spots，你的attention is selecting focus zones。The "stable" text is continuous creative achievement of你的visual collapse system。This understanding transforms how you see everything：instead of passive recording，recognize active construction；instead of believing eyes completely，appreciate brain's creative interpretation；instead of taking vision for granted，marvel at constant collapse stabilization occurring。Every visual moment is creative act—你participate in making reality appear through choices about where to look，how to focus，what to notice。This is profound responsibility：你的seeing partly creates what becomes visible in world。Choose你的visual attention wisely—it shapes not only你的experience but influences what aspects of reality get stabilized for others too。Beauty emerges when visual collapse aligns with harmony，truth appears when seeing transcends preconceptions。
