Identification of Tipcap of Agricultural Kernel Based on Harris Algorithm

Abstract:

By analyzing morphological feature of tipcap of agricultural kernel, a tipcap identification algorithm based on Harris corner detector was developed. Harris algorithm detected the corner within a local region. As the most obvious corner structure, the tipcap had the maximal response to Harris corner detector, which made it can detect the kernels without the obvious tipcap accurately. The kernels with tipcap of corn, pumpkin and summer squash were selected for the test. The experimental results on 750 kernels showed that the proposed method got overall accuracy of 95.6% for tipcap of kernels.
