| Abstract/Contents: | "Near Infra Red (IR) photography has been used for the collection of plant stress data for many years. IR film and video cameras have comparable IR sensitivity. The purpose of this research was to evaluate the use of video for IR image acquisition and a digital analysis system for IR photographs. IR film gives a 6000x4000 pixel image when digitized. This contrasts to the 512x512 pixel image gathered by common video cameras. A 512x512 image does not have sufficient resolution to allow detection of subtle patterns that are signatures of plant stress. Video methods are limited to 256 shades of grey, due to expense of equipment capable of analyzing real time color video. The superior color and spatial resolution of IR film, in combination with the relatively low cost of photographic cameras and the maturity of the interpretation systems, makes current photographic methods the technique of choice for detecting plant stress on golf courses." |
