Stem and Calyx Identification of 3D Apples Using Multi-Threshold Segmentation and 2D Convex Hull

Stem and Calyx Recognition on ‘Jonagold’ Apples by Pattern Recognition

In this paper, a novel method to recognize stem or calyx regions of ‘Jonagold’ apples by pattern recognition is proposed. The method starts with background removal and object segmentation by thresholding. Statistical, textural and shape features are extracted from each segmented object and these features are introduced to several supervised classification algorithms. Linear discriminant, neares...

on the equivalence of constructed-response and multiple-choice : stem-equivalent, stem non-equivalent but content equivalent, and stem and content non-equivalent items in reading comprehension using multifaceted rasch

the present study investigated construct equivalence of multiple choice (mc) and constructed response (cr) item types across stem and content equivalent mc and cr items (item type ‘a’), non-stem-equivalent but content equivalent mc and cr items (item type ‘b’), and non-stem and non-content equivalent mc and cr items (item type ‘c’). one hundred seventy english-major undergraduates completed mc ...

Measuring Interval Efficiency in Convex Hull of Data Using DEA

Hand Segmentation Using 2D/3D Images

This paper describes a fast and robust segmentation technique based on the fusion of 2D/3D images for gesture recognition. These images are provided by the novel 3D Time-of-Flight (TOF) camera which has been implemented in our research center (ZESS). Using modulated infrared lighting, this camera generates an intensity image with the range information for each pixel of a Photonic Mixer Device (...
