    A prototype weight-based yield mapping system for seed corn production was developed at the University of Tennessee (UTK) and field tested in Iowa. The first chapter of the following study focuses on assessing the accuracy of this yield mapping system which employs a novel yield prediction and analysis software called Yield Analyzer. Yield Analyzer was designed using a rule-based system for producing yield maps with minimal user input by automatically determining acceptable ranges for known dependent variables that contribute to dynamic weight measurement errors. The second chapter of this thesis covers the development of a non-intrusive, machine vision technique to measure true width of crop entering a header during harvesting. The development of this technology would further contribute to the overall yield prediction accuracy by providing necessary information for calculating real-time changes in the area component of yield. Using a rule-based system for yield data processing, Yield Analyzer produces two levels of site-specific yield measurements. At the first level of data acquisition, cart weight measurements compared to certified scale weights at an average absolute difference of 6.07 %. At the second level of data acquisition, weight, length, and yield measurements had a higher degree of variance. For determination of effective header width, two vision-based classification methods were tested from real-time harvesting video data. The first method used color features for crop detection performed \u3e 90 % accuracy at 0.50 - 0.75 standard deviations from mean color feature descriptors. A linear support vector machine classifier trained with image SURF descriptors performed at \u3e 95 % classification accuracy when images from the entire video dataset were used for training

    Pakistan is an agricultural country. Sun flower is the major crop of Pakistan which is being sowing in many areas of country. It fulfills the requirement of edible oil. In this paper we are trying to identify the best quality from different sun flowers seeds verities by using machine learning approaches. We take the images of four kinds of sunflower seeds which names Top sun(A), High Sun(B),US666(C) and Seji(D) for classification. We get eight different images of each kind of sunflower. In this paper sun flowers seeds varieties were categorized by using Computer vision image processing tool (CVIP). The experience and knowledge of inspectors are required to perfectly perform this assessment process. We use the RST-Invariant Features, Histogram Features, Texture Features, and Pattern Classification and also use the nearest neighbor and k-nearest neighbor algorithms for final classification. We achieved the final results of four kinds of sunflower using nearest neighbor on distance one and two 89% and 72% average and on k-nearest neighbor 89% and 73% average percentage. These are the best percentage results using these algorithms for classification. In this way we can easily classify the sunflower seeds and also these methods provide opportunity to farmer and other people for identify and select the different better and healthy sunflower seeds for better benefits.

    There are about 90 different varieties of chickpeas around the world. In Iran, where this study takes place, there are five species that are the most popular (Adel, Arman, Azad, Bevanij and Hashem), with different properties and prices. However, distinguishing them manually is difficult because they have very similar morphological characteristics. In this research, two different computer vision methods for the classification of the variety of chickpeas are proposed and compared. The images were captured with an industrial camera in Kermanshah, Iran. The first method is based on color and texture features extraction, followed by a selection of the most effective features, and classification with a hybrid of artificial neural networks and particle swarm optimization (ANN-PSO). The second method is not based on an explicit extraction of features; instead, image patches (RGB pixel values) are directly used as input for a three-layered backpropagation ANN. The first method achieved a correct classification rate (CCR) of 97.0%, while the second approach achieved a CCR of 99.3%. These results prove that visual classification of fruit varieties in agriculture can be done in a very precise way using a suitable method. Although both techniques are feasible, the second method is generic and more easily applicable to other types of crops, since it is not based on a set of given features.This research was funded by the Spanish MICINN, as well as European Commission FEDER funds, under grant RTI2018-098156-B-C53. It has also been supported by the European Union (EU) under Erasmus + project entitled "Fostering Internationalization in Agricultural Engineering in Iran and Russia [FARmER]" with grant number 585596-EPP-1-2017-1-DE-EPPKA2-CBHE-JP

    Volunteer potato is an increasing problem in crop rotations where winter temperatures are often not cold enough to kill tubers leftover from harvest. Poor control, as a result of high labor demands, causes diseases like Phytophthora infestans to spread to neighboring fields. Therefore, automatic detection and removal of volunteer plants is required. In this research, an adaptive Bayesian classification method has been developed for classification of volunteer potato plants within a sugar beet crop. With use of ground truth images, the classification accuracy of the plants was determined. In the non-adaptive scheme, the classification accuracy was 84.6 and 34.9% for the constant and changing natural light conditions, respectively. In the adaptive scheme, the classification accuracy increased to 89.8 and 67.7% for the constant and changing natural light conditions, respectively. Crop row information was successfully used to train the adaptive classifier, without having to choose training data in advanc
