The aim of a multispectral system is to recover a spectral function at each image pixel, but when a scene is digitally imaged under a light of unknown spectral power distribution (SPD), the image pixels give incomplete information about the spectral reflectances of objects in the scene. We have analyzed how accurately the spectra of artificial fluorescent light sources can be recovered with a d...

This article aims to provide a new and fast method for differentiation of inks on a questioned document. The data acquisition was carried out by designing specific image analysis software for evaluating thin layer chromatograms (TLC-IA). The ink spot was extracted from the document using methanol and separated by TLC using plastic sheet silica gel 60 without fluorescent indicator, and a mixture...

Aerial photography acquired with unmanned aerial vehicles (UAVs) has great potential for incorporation into rangeland health monitoring protocols, and object-based image analysis is well suited for this hyperspatial imagery. A major drawback, however, is the low spectral resolution of the imagery, because most lightweight cameras suitable for UAVs only acquire imagery in the red, green, and blu...

In this paper we present the utilization of high-spectral resolution imagery for improving low-spectral resolution imagery. In our analysis, we assume that an acquisition of high spectral resolution images provides more accurate spectral predictions of low spectral resolution images than a direct acquisition of low spectral resolution images. We illustrate the advantages by focusing on a specif...

This paper describes the process of classifying color images based on color texture information. The images are originally in Red-Green-Blue (RGB) and they are changed to xyY to facilitate the image processing. Chromacity information (xy) is combined with luminance (Y) in the image. Luminance and chrominance image processing implementation is included in this paper. The process analyzes them se...

Recently solution scanometry, as a new, simple, fast, portable, and economic method was introduced for determination of acidity constants of indicator and dyes. In this study, a method was applied for the determination of the acidity constant of p-Rosolic acid (RA) and Bromoxylenol blue (BXB) indicators. The method is based on scanning of Plexiglas® sheet containing colored solutions with a fla...

Digital Image Watermarking plays an important role when it comes to maintaining digital color picture authentication information. The proposed paper consists mainly of a watermarking scheme consisting discrete wavelet transformation and involving the generation pn sequence number embed watermark also extract from host image. technique suggested includes both embedding removing file. Both method...

Crystal guava is one of Indonesia's flora diversity. The rind the unripe crystal fruit green, and ripe yellowish green. However, it difficult to determine ripeness due similar color skin. Determining uncertain therefore requires a way deal with this uncertainty. One methods you can use fuzzy Mamdani. In study, level determined using fruits fall into four categories: raw, half ripe, very ripe. d...

Spectral investigation of the canopy has an increasing importance in precision viticulture to monitor effect biotic and abiotic stress factors. In this study, RGB (color model, red, green, blue)-based vegetation indices were evaluated find a correlation with grapevine leaf chlorophyll concentration. ‘Hárslevelű’ (Vitis vinifera L.) samples obtained from commercial vineyard digitalized. The conc...

Since corn is the second most widespread crop globally and its production has an impact on all industries, from animal husbandry to sweeteners, modern agriculture meets task of preserving yield quality detecting stress. Application remote sensing techniques enabled more efficient monitoring due ability cover large areas perform non-destructive non-invasive measurements. By using vegetation indi...
