[12) Leach T.and Padgett M.J., 2003, New ]. Phys., 5 154 increased to make the largest of them fully saturated whilst maintaining their ratios. Figures 2 and 3 show our experimental results. Figure 2 contrasts the case where the optical vortices for each spectral component in the white-light source are overlapping and not overlapping. When the vortices are not overlapping, the chromascope image...
The most important part in forest inventory based on remote sensing data is individual tree identification, because only when the tree is identified, we can try to determine its characteristic features. The objective of research is to explore remote sensing methods to determine individual tree position using LIDAR and digital aerial photography in Latvian forest conditions. The study site is a ...
AIM To validate high definition endoscopes with Fujinon intelligent chromoendoscopy (FICE) in colonoscopy. METHODS The image quality of normal white light endoscopy (WLE), that of the 10 available FICE filters and that of a gold standard (0.2% indigo carmine dye) were compared. RESULTS FICE-filter 4 [red, green, and blue (RGB) wavelengths of 520, 500, and 405 nm, respectively] provided the ...
Existing methods for fall detection may not detect a when it occurs or generate false alarm does occur. In order to overcome these limitations and falls with 100% accuracy, double-check method in elderly people via an inertial measurement unit-location (IMU-L) sensor red-green-blue (RGB) camera is proposed. The IMU-L combination of IMU (accelerometer gyroscope) ultrawideband signal-based locati...
Videos and still-images play quite important role in telemedicine, such as dermatology, teleconsultation, endoscopy, and surgery video. However, one of the problems is the lack of color reproducibility, since it is difficult to reproduce the original color of the object in conventional color imaging systems based on RGB (red, green, blue). Although the color management technology enables to dea...
We propose a novel method to analyze a sequence of color images. A series of color images is examined in a four-dimensional space, which we call the temporal-color space, whose axes are the three color axes red, green, and blue and one temporal axis. The significance of the temporal-color space lies in its ability to represent the change of image color with time. A conventional color space anal...
In this research, we presented another implanting calculation for QR Code Image Steganography and Text Hiding, which is based on 3-discrete wavelet transform (DWT) and improved RSA algorithm. Firstly, enter the text message and choose four random numbers for RSA encryption. After that, take four pictures: one is cover image and another is secret image. In the process of embedding, we divide RGB...
In this paper, we report on a printable glass-based manufacturing method and new proof-of-concept colorimetric signal readout scheme for dielectric barrier discharge (DBD)-type helium plasma photoionization detector. The sensor consists of millimeter-sized glass chamber manufactured using suspension. Plasma inside the chip is generated custom-built power supply (900 V 83.6 kHz), detector uses ∼...
estimation of pigment magnitudes in synthetic leather by using scanner and artificial neural network
in the present work the magnitudes of pigments in the synthetic leather, were measured by means of scanner. initially synthetic leather samples pigmented by three different pigments of yellow, blue and red colors were prepared. then the pigmented samples were scanned, and the values of rgb of images were calculated. the artificial neural network (ann) method used to make relation between rgb va...
o m p p c B bstract. This paper proposes a driving current control method for back light unit (BLU), consisting of red, green, and blue (RGB) ight-emitting diodes (LEDs), whereby a RGB optical sensor is used o check the output color stimulus variation to enable a time-stable olor stimulus for light emission by the RGB LED BLU. First, to btain the present color stimulus information of the RGB LE...
