Presentation Transcript

  1. A Model of Saliency-Based Visual Attention

  2. 大綱 • ITTI Model • ITTI金字塔作用 • Linear filtering作用 • Gabor filters作用 • Matlab ITTI getFeatureMaps程式碼流程 • getFeatureMaps的值

  3. ITTI Model

  4. ITTI金字塔作用 • 長寬比率縮減2次方，透過低頻過濾器和子取樣（subsample） • 藉以取得圖片中大結構或大細節的相關資訊，以進一步作影像處理

  5. Linear filtering作用 • 設定blur 值,將輸入影像模糊化,使影像細節只保存強度值較大的細節

  6. Gabor filters作用 • Itti model是multi-channel,itti model的gabor filter公式，遵循Object Detection using Gabor Filters的實驗結果。 • 加入相位參數，特定的向量方位在filter過程中，資料能被保存下來。

  7. ITTI範例

  8. Matlab ITTI getFeatureMaps程式碼流程

  9. getFeatureMaps的值 • 為矩陣資料型態
