under plane-polarized (PPL) and cross-polarized (XPL) illumination modes. Any unknown mineral is registered by two 19-point sets (under PPL and XPL) in the CIELab color space and the proposed scheme tracks mineral color variations in the CIELab color...

with BRISK, and MSER with FREAK was evaluated. The included color spaces were HSV, H, YCbCr, Y, NTSC and RGB. The performance comparison for each combination was carried out in terms of precision and recall values using stereo image pairs of tree...

Abstract—one of the best way to clustering in color images is

to transform R, G, B color space into the target color space by

linear transformations that are captured by 3×3 matrices. The

Main target of this paper is introducing...

Abstract: Each three-component collection such as {Red, Green, Blue} (RGB), and {Luminance Y,

Chrominance Cr, Chrominance Cb} (YCbCr) is termed as a color space. Many color spaces are related to each

other by linear transformations...

the rule of between pixels of mouth and other

pixels an optimized map. The image is

mapped to YCbCr color space. The main idea

of the method is based on that Mouth has the

high values of Cr and low values of Cb. The...

در زمینه‌ی کشاورزی، نظارت منظم و دوره‌ای جهت کنترل سلامت و کیفیت گیاهان امری ضروری است. اندازه‌گیری مقدار کلروفیل و کارتنوئید برگ به‌عنوان یکی از شاخص‌های سلامت محصول محسوب می‌شود. در این پژوهش مجموعه‌هایی از تصاویر برگ‌های ...
