A computer vision system for separation of bulbs from tulips is described, the algorithms of which are based on laboratory, field and literature data. Program system were developed from this system. Developed visual system include light chamber, Closed circuit digital CCD monochrome videocamera, video interface board and personal computer. The basic elements of the computer programs are: multitask kernel, drivers, hardware, software, engineering process and applied programs. Linear discriminant analysis (LDA) classifiers are used for separation and evaluation of 4 bulb groups. The separation errors were determined.

Key words: computer vision, pattern recognition, linear discriminant analysis
