For sustainable development in field of agriculture continuous cropping must be accompanied with constant check of fertility value of soil. Soil nutrient measurement is very necessary for proper plant growth and effective fertilization. For this the soil samples are sent to the soil testing labs for test. In these labs the nutrient proportion is determined by mere observation of the colour of the...
Human skin color has been studied as biometric indicator, most of previous researches studies focused in using skin color to detect the face, human and human motion. The objective of this article is to evaluate the variation in human skin color as a unique code for identification purpose. Fifty picture of the nose were captured using a mobile camera with a resolution of 3 mega pixel. Part of the nose...
Based on ARM9 platform and the Linux operating system, this article studied on the methods of the video image capture and decoding. Take USB-camera image acquisition and image decoding for example, FrameBuffer and Video4Linux, two system interfaces for video image processing under the Linux operating system are introduced, and the collected images transferred from JPEG format to RGB format is displayed...
This paper has presented and designed a four-channel video data system of reception, extraction, display and switch based on the DE2-70 development and education board and the development environment of embedded operating system μClinux. First, it received the video data packets, which were 640×480 resolution and RGB format coming from the four cameras in front-end through the router on network, and...
In this study, an image processing algorithm is developed for epiretinal implants. In this algorithm, it is presented an approach for adaptive frequency control that is one of the important parameters to generate stimuli. Standard 240times320 pixels video images in RGB format are processed as 10times10 pixel blocks. Consequently, it is designed to activate 24times32 pixels electrode matrix. As a retinal...
Telepresence refers to the impression of being in an environment generated by multi-media technology. In this article, the capturing system for a real-time telepresence environment is presented. A fully scalable architecture is proposed allowing the control of a large number of cameras with a low-cost platform and only one PC. The system will capture, transform and calibrate the video from the cameras...
The aim of this work is to show the computational cost of implementing an conversion algorithm of Bayer format to RGB format by the method of bilinear interpolation, taking into consideration the correlation. This study demonstrates that in some applications the converter is not necessary, as in the case of real time tracking of different species, particularly in the subtraction and blurring of images...
Reliable touch-less fingerprint recognition still remains a challenge nowadays as the conventional techniques that used to preprocess the optical or capacitance sensor acquired fingerprint image, for segmentation, enhancement and core point detection, are inadequate to serve the purpose. The problems of the touch-less fingerprint recognition are the low contrast between the ridges and the valleys...
