In this paper we propose an automatic algorithm able to classify legume leaf images considering only the leaf venation patterns (leaf shape, color and texture are excluded). This method processes leaf images captured with a standard scanner and segments the veins using the Unconstrained Hit-or-Miss Transform (UHMT) and adaptive thresholding. We measure several morphological features on the vein...

People form associations between colors and entities, which influence their evaluations of the world. These evaluations are dynamic, as specific associations become more or less active in people's minds over time. We investigated how evaluations of colors (color preferences) changed over the course of fall, as color-associated fall entities became more prevalent in the environment. Participants...

An eye-contact display and camera system for video telephony is described in which a video camera looks through a conventional active matrix LC display. By removing the rear polarizer from the display, the camera can look through the display without seeing the information on the display. Display/camera multiplexing and color are achieved via a polarized projection illumination system. Color tri...

To establish a proteomic reference map for soybean leaves, we separated and identified leaf proteins using two-dimensional polyacrylamide gel electrophoresis (2D-PAGE) and mass spectrometry (MS). Tryptic digests of 260 spots were subjected to peptide mass fingerprinting (PMF) by matrix-assisted laser desorption/ionization-time of flight (MALDI-TOF) MS. Fifty-three of these protein spots were id...

Image segmentation is the most challenging issue in computer vision applications. And most difficulties for crops management in agriculture are the lack of appropriate methods for detecting the leaf damage for pests’ treatment. In this paper we proposed an automatic method for leaf damage detection and severity estimation of coffee leaf by avoiding defoliation. After enhancing the contrast of t...

Chinese cabbage buds were soaked with Ethyl methanesulfonate (EMS) to induce mutagenesis. The influence of different EMS concentrations and treatment durations on microspore development, embryo production rate and seedling rate were evaluated in five Chinese cabbage genotypes. Mutations in four color-related genes were identified using high resolution melting (HRM) curves of their PCR products....

Plant diseases have become an important issue because they cause important reduction in each quality and amount of agricultural products. Automatic detection of plant diseases is an important analysis topic because it could significantly help in observation giant fields, and enable automatic detection the symptoms of diseases as soon as they appear on the plant leaves. In this paper an algorith...

Background and objectivesNatural products from plants their biological potentialities have increased environmental concerns. This study aimed to evaluate the phenolic composition, along with antioxidant, antimicrobial, insecticidal activities of Ziziphus spina-christi leaf extracts using LC-MS.

Abstract Leaf compounds may contribute to plant defense against Cronartium rusts. Secondary are either natural or induced in leaves. We studied the variation of leaves six alternate hosts pini and two C. ribicola that represented susceptible resistant species these Extracts from were analyzed using LC-MSMS (liquid chromatography tandem mass spectrometry) compared between same genera identify si...
