“…Machine vision applications in grading and sorting of vegetables and fruits based on size, color, weight, and defects were stated in the literature (Chen and Sun, 1991;Abbott, 1999;Chen et al, 2002;Mahendran et al, 2012;Vibhute and Bodhe, 2012). In the case of potatoes, there is a considerable variation of size, shape, and color of the cultivars available in the local market which adds difficulty for building a robust, yet universal sorting machine that can tolerate such changes.…”

“…These findings on color preferences are adopted in the concept of quality classification of Snap beans and Long beans as the subjects of the study. Image processing through computer technology defines as the process of applying methods to run machines in an automatic inspection using an imaging-based, process control and robot monitoring systems in industrial applications [5]. Computer-aided technology was used to acquire and analyze images of actual scenes to process machines.…”

The Philippine Council for Agriculture, Forestry and National Resources Research and Development-Department of Science and Technology (PCAARRD-DOST) have recognized the importance of cultivating legumes as priority crop among others in the vegetable industry under the National Vegetable Research & Development Program. They have further emphasized the need for innovating the methods to improve the processes in terms of producing better quality of products. The study developed a prototype compiled application based on the trained and validated dataset using ANN (Artificial Neural Network) machine. The BoF (Bag of Features) technique was utilized for image features extraction in the SVM (Support Vector Machine) environment for quality classification of Phaseolus Vulgaris family of legumes. These are commonly cultivated in the Philippines. The combined methods yielded an accuracy of 90.2%.

“…Although the mechanism of foam formation is still to be fully understood, foam stability seems to be positively affected by surface-active hop-derived bitter acids and malted barley-based hydrophobic/amphipathic proteins or polypeptides (Asano and Hashimoto 1980;Bamforth 2004;Evans and Bamforth 2009;Kunimune 2007). Yet, it might be also influenced by several minor physical, chemical, and brewing/ malting process factors, such as ethanol concentration, pH, lipids, and high gravity mashing.…”

Beer foam is one of the first characteristics consumers visually perceive. Even if their opinions vary, generally, beer foam should be stable and long lasting. In this work, the conventional foam head retention method developed by Rudin (1957) was improved by resorting to three different automatic data acquisition systems. The first one made use of a mouse time tracking software offered at no cost. The second one was an Accurate Image Analysis system using a high-definition camera and a script written in MATLAB. Finally, the third one was an automatic low-cost image analysis (LCIA) system incorporating a Raspberry Pi single-board computer and a camera module (Raspberry Pi Foundation, UK). The latter was able not only to acquire the whole foam decay curve but also to fit the time course of the beer-foam interface position and extract the characteristic beer foam halflife (t ½ ). All the data acquisition systems yielded t ½ values practically coincident at the probability level of 0.05, this confirming their substantial equivalence. Once the lager beer had been laced with increasing doses of a foam agent (i.e., tetrahydro-iso-α-acid) to enhance its foam persistence, the resulting foam half-life, as estimated using the above Rudinbased methods, was highly correlated (r 2 = 0.99) to the foam collapse time, as derived from the NIBEM Foam Stability Tester. Finally, thanks to the LCIA acquisition system developed here, the Rudin test might represent a fast, flexible, and cheaper alternative to the generally recommended but expensive NIBEM tester, as well as other commercial automated Rudin apparatuses.
