[編輯] Spatial Vision and Form Perception
- 一張圖片開始
- Dr. Angry and Mr. Smile:Philippe G. Schyns*, Aude Oliva*
- 視覺三大工作(辨識上)
- Detection(偵測)
- Pick out and object from its surroundings.
- Discrimination (區分)
- Distinguish one from another.
- Identification (識別)
- Identify particular object (or person).
- 日常生活的視覺
- 在擁擠的停車場內尋找紅色的Miata車子(課本例子)
- Discriminate red from others
- Identify your car from others
- 這些是瞬間、輕易完成
- Visual difference
- Color
- Movement
- Shape
- Depth
- Spatial properties(空間特性)
- Form, visual pattern(視覺空間樣式?)
- Early vision(「神經」早期視覺)
- Spirit in Mars
- 2004-1-4
- Spirit
- 登陸艇
- 機械臂
- Adirondack
- 形狀類似美國阿爾崗金族印第安人的帳篷故得名
- get a X-ray
- What defines 『form』?
- Have any Universal law for form?「形狀」有普世規則嗎?
- Component(基本元件) of form
- Analytic introspection(內省分析法)
- Structuralist的手段
- 曾經發現40,000個sensational element(感覺元素) (Boring, 1942)
- Local analysis
- scale
- Coarse scale and fine scale
- Smile woman(coarse) and unsmile man(fine)
- puzzle in fine
- puzzle in coarse
- What is the unit of scale?
- What are gratings?
- Four defining characteristics(特徵)
- Saptial frequency(空間頻率)
- Cycles per degree (visual angle)
- 在一臂之遠圖5.6具有1.0cycle/degree
- Contrast(對比)
- Orientation(方位)
- Spatial phase(空間相位)
- Gratings and contrast sensitivity
- Fourier analysis
- Discrete Fourier Transform analysis 間斷傅立葉傳換分析
- Human contrast sensitivity function(對比敏感函數)
- Contrast thresholds and contrast sensitivity function (CSF)
- Photopic mesopic and scotopic
- Species difference(種間差異) —experiment
- Species difference—data
- infant view—preference looking
- aging
- Structural basis of CSF
- selective adaptation(選擇性適應)
- Selective adaptation
- Effect of spatial frequency
- Low and high
- Mosaic 瑪塞克
- How to make mosaic
- Discrimination??
- Contour and SF
- size after effect(大小後效)
- 實驗
- limit for discrimination
- orientation / size difference
- texture difference
- texture
- figure and ground(圖形與背景)
- Treisman's experiment
- Pop-up effect(跳出效果)
- Artist Ellsworth Kelly(1950)
- 3D structure (Op art)
- configural superiority(結構優勢)
- experiment of Pomerantz (1981)
- Gestalt
- Köhler (1920)
- 我們不是在看每一片斷的東西;而是在看各部分間以某一些特定關係與其他部分聯結的結果。
- configural superiority 可以用以上的話來思考
- Gestalt principles
- Proximity(接近律)
- Proximity – Glass pattern
- Similarity(相似律)
- Closure (封閉律)
- good continuation (好的連續)—in nature
- good continuation—Geisler's model
- Geisler's model—computer vs human
- does proximity promote or retard distinguish ?(接近律是增加或阻礙區分?)
- Symmetry(對稱律)
- symmetry / complexity
- symmetry reduce complexity
- Symmetry
