Threshold-Examples

OpenCV + Python

src = Imagem atual
dst = Imagem de destino

Binary Thresholding ( type = THRESH_BINARY )

if src(x,y) > thresh
    dst(x,y) = maxValue
else
    dst(x,y) = 0

Inverse Binary Thresholding ( type = THRESH_BINARY_INV )

if src(x,y) > thresh
  dst(x,y) = 0
else
  dst(x,y) = maxValue

Truncate Thresholding ( type = THRESH_TRUNC )

if src(x,y) > thresh
  dst(x,y) = thresh
else
  dst(x,y) = src(x,y)

Threshold to Zero ( type = THRESH_TOZERO )

if src(x,y) > thresh
  dst(x,y) = src(x,y)
else
  dst(x,y) = 0

Inverted Threshold to Zero ( type = THRESH_TOZERO_INV)

if src(x,y) > thresh
  dst(x,y) = 0
else
  dst(x,y) = src(x,y)
