Dementia-Care-Vision-Beta

• This research is still under development and will be published soon.

Abstract

• Develop a bed exist monitor by PIR camera
• Analyze sleeping quality in computer vision viewpoint

Progress so far

1. Image Prerpocessing

a. Magic Eraser

• Purpose: Solving noise pixel caused by PIR camera
  

• Method:

  • step1: Go through all single pixel
  • step2: Calculate the difference between the current point and the surrounding points
  • step3: If all difference > threshold, let current pixel = all surround pixels’ average

• Results:

2. Moving Detection

• Purpose: Making sleeping quality analysis
  

• Method:

  • Compare "mask image" similarity (SSIM)
  • Why using mask image? => to remove the factors(brightness and contrast) that will affect SSIM, only remain the pattern structure

• Result 1: Mask Image

• Result 2: Compare SSIM discrete level of using mak image and raw image (red dots: mask image, blue dots: raw image)

• Result 3: Claculate moving times

• Result 4: Calculate moving degree

Next Step

=> Creating multiple input and single output model
