This chapter has been an opportunity to consider the inputs of a computer vision system at the hardware and software levels. Also, we have addressed the need to efficiently marshal image data from the input stage to the processing and output stages. Our specific accomplishments have included the following:
- Understanding differences among various wavelengths of light and radiation
- Understanding various properties of sensors, lenses, and images
- Capturing and recording slow-motion video with the PlayStation Eye camera and OpenCV's videoio module
- Comparing subjects' appearance in visible and NIR light using the ASUS Xtion PRO Live camera with OpenNI2 and OpenCV's highgui module
- Capturing and rendering HD video at high speed while detecting faces, using FlyCapture2, OpenCV, SDL2, and the GS3-U3-23S6M-C camera
- Shopping for cheap, old, used lenses that are surprisingly good!
Next, in Chapter 2, Photographing Nature and Wildlife with an Automated Camera, we will deepen our appreciation of high-quality images as we build a smart camera that captures and edits documentary footage of a natural environment!
