The flower bud ratio is an important criteria and nodus in flower automatic grading realization, however using computer vision to detect flower bud still remains a challenge. This paper presents a flower bud detection model as a resolution: By using spectral residual method to calculate saliency map and using SURF feature-points, we can quickly and unambiguously obtain the SURF histogram, then construct the flower bud detection model with SVM. The experiments indicates that the flower bud detection model which provides an effective way for measuring bud ratio in flower automatic grading system can distinguish between bud and bloom with good results.
