The usefulness of nondestructive methods for measuring chlorophyll content in skin of ‘Golden Delicious’ apples and for evaluating quality parameters and fruit maturity using optical reflectance spectrometry was studied. The fruit weight, firmness, total soluble solids content and titratable acidity during vegetation period and short-term storage at 10°C of ‘Golden Delicious’ apples were measur...

This paper presents apple grading into four classes according to European standards. Two varieties were tested: Golden Delicious and Jonagold. The image database included more than a 1000 images of fruits (528 Golden Delicious, 642 Jonagold) belonging to the three acceptable categories}Extra, I and II}and the reject (each class represents, respectively, about 60, 10 and 20% of the sample size)....

Firmness is an important parameter in determining the maturity and quality grade of apple fruit. The objective of this research was to mprove the multispectral imaging system used in our previous studies and refine scattering analysis methods for more effectively measuring pple fruit firmness. An improved multispectral imaging system equipped with a light intensity controller was used to measur...

ABSTRACT- The evaluation of leaf area and leaf nutritional value is important for crop growth modeling and estimations of its performance. The purpose of this study was to use image processing techniques to develop an economical method to ease the assessment of nutrient status and leaf area (LA) of plants and to compare the outcomes of this method with linear models. Leaf area and leaf chloroph...

The sequence of events which occurs during the ripening of the Passe-Crassane pear fruit have been previously studied. In this work, we have investigated the ripening of another climacteric fruit (Pyrus malus L. cv Golden Delicious) and of a nonclimacteric fruit (Prunus avium L. cv Bigarreau Napoléon). We show that both climacteric fruits exhibit the same preclimacteric sequence of events. Diff...

Apel merupakan varietas buah yang memounyai banyak jenis. Aple ang secara visual tampak sama, bisa jadi variates berbeda misalnya jenis apel Grany smith, golden dan malang. Ketiga tersebut sama-sama berwarna hijau. Secara kasat mata warna saja tidak cukup untuk mengklasifikasi, sehingga perlu adanya pemnafaatan teknologi dapat membantu proses klasifikasi menjadi lebih akurat. Pengolahancitra di...
