Portable Pixelmap (PPM)
  • PPM is a type of image file format.
  • Each pixel can be easily manipulated since it is in an understandable format.

Start ASCII PPM file format

grayscale
Grayscale
  • Every colour image a pixel consists of 3 values; red, green and blue.
  • A Grayscaleimage value of each pixel is the same.
  • To convert pixel colour to its appropriate level of grey, the following calculation is needed.

Greyscale

Red X 30%

Green X 59%

Blue X 11%

skin colour detection
Skin colour detection
  • This is used to identify whether a set of pixels is a potential skin area.
  • Convert from RGB to HSV colour space.
  • The threshold values is used to distinguish between skin and non skin pixels.

  • The skin colourdetection will be used to identify whether a person has been detected in a video.
