Automated image measurements perform at least as well as manual measurements. Overall costs between manual (more recording) and imaged (more collection) measurements are about the same – but IA enables measured characters to be recorded which could not be done manually (e.g. leaflet area). Image library becomes available 1) For reference; 2) For data checking 3) for subsequently developed characters Other remark: We have downloaded a copy of the freely available software and have used it to investigate the possibility of assessing seed shape in large seeded crops but as yet we have not used this method in relation to variety testing.

A reference object is incorporated into every picture. The IA program links with the studio Controller. The controller has special routines to handle camera aperture white noise etc. The linkage program has been specifically adapted by a consultant to allow menu driven options for each crop and to allow the entry of plot numbers. Once the controller has taken a picture the file is 300 GB downloaded and re- opened by the IA program running in the background. The IA program will automatically analyze the picture and store the results in a data file. This allows the user to move any touching or irregular objects, thus equating to a live system. However the Controller can be used in isolation, storing the images to be batch processed at a later time. Once all plots have been photographed and analyzed via the batch process, thumbnail images can be examined and any outliers can be removed. [Annex II follows]
