基于空间频域成像的果蔬皮下隐性损伤可视化检测
Visual Detection of Subsurface Bruising in Fruits and Vegetables Based on Spatial-Frequency Domain Imaging
摘要
Abstract
It is challenging to identify the features of subsurface fresh bruises of fruits and vegetables by traditional uni-form imaging techniques due to the mild symptoms.Owing to the capability of depth-varying and signal-enhanced char-acterization,spatial-frequency domain imaging was used to detect the fresh bruising(within 30 minutes)of 10 kinds of fruits and vegetables(carrot,Fuji apple,cucumber,golden delicious apple,fruit cucumber,delicious apple,mango,yellow peach,rose plum,and honey peach).Through the procedures of image acquisition,image demodulation,white-board correction and inverse estimation,optical properties of the fruits and vegetables were obtained.The results indicat-ed that there were great differences of optical properties between non-bruised and bruised samples,with decreased values of reduced scattering coefficients for the bruised ones,which visually realized the non-destructive detection of early bruising.The novel method proposed in this paper is promising for non-destructive detection of early bruising of fruits and vegetables.关键词
