Most colour‐normal human observers have no difficulty to adjust a coloured light such that it appears neither red nor green, or such that it appears neither yellow nor blue. Moreover, it has been shown that these hue judgements are not significantly influenced by language or age and individual differences in colour sensitivity are not reflected in the unique‐hue settings. Here we ...

This paper proposes a new method of color image segmentation considering both global information and local homogeneity. The method applies the mean shift algorithm in the hue and intensity subspace of HSV. The cyclic property of the hue component is also considered in the proposed method. Experiments on natural color images show promising results.

This paper presents an image analysis algorithm to detect and count yellow tomato flowers in a greenhouse with uneven illumination conditions, complex growth conditions and different flower sizes. The algorithm is designed to be employed on a drone that flies in greenhouses to accomplish several tasks such as pollination and yield estimation. Detecting the flowers can provide useful information...

In this study, it was aimed to examine and compare the effects of Hibiscus (Hibiscus sabdariffa L.) poppy (Papaver rhoeas extracts on some chemical, physical, microbiological sensory properties bread dough bread. The pH, L, b, chroma, hue values decreased by usage hibiscus extract, while a value increasing. It determined as lowest pH 4.13; L 39.23; b 5.08; chroma 6.55, angle 54.65 highest 7.20....

Edible films and coatings have currently received increasing interest because of their potential in food applications. This study examined the effect incorporated essential oils natural plant extracts on characteristics composite seaweed hydrocolloid gac pulp films. Films were prepared by a casting technique, followed measurement physical, optical, barrier, mechanical, structural properties. Th...

This study was conducted to evaluate the effect of frozen storage time (30, 60, 90 or 180 days) and cooking (100 °C, 30 min) on the physical characteristics and oxidative stability of M. Gastrocnemius pars interna (GN) and M. Iliofiburalis (IF) of rhea americana. Physical parameters measured included thawing and cooking loss, colour parameters (L*a*b*), while oxidation was assessed by determini...

Three modes of visible-near infrared spectroscopic measurement (reflectance, interactance and transmission) were compared for their ability to non-destructively estimate harvest soluble solids content (SSC), density and internal flesh colour of the yellow-fleshed kiwifruit Actinidia chinensis. Interactance mode spectra provided the most accurate estimates of SSC, density and flesh colour. SSC w...
