The current standard procedure for aligning thermal imagery with structure-from-motion (SfM) software uses GPS logger data for the initial image location. As input data, all thermal images of the flight are rescaled to cover the same dynamic scale range, but they are not corrected for changes in meteorological conditions during the flight. This standard procedure can give poor results, particul...

We present an optimization technique to find hue constant RGB sensors. The hue representation is based on a log RGB opponent color space that is invariant to brightness and gamma. While modeling the visual response did not derive the opponent space, the hue definition is similar to the ones found in CIE Lab and IPT. Finding hue constant RGB sensors through this optimization might be applicable ...

— In this methodological paper, provided with a relevant survey value, an original low-level computer vision (CV) software pipeline, called RGB Image Automatic Mapper (RGBIAM), is presented and discussed. RGBIAM is a lightweight computer program capable of automated near real-time superpixel detection and quality assessment in an uncalibrated monitor-typical red-green-blue (RGB) image, depict...

We introduce the concept of dynamic image, a novel compact representation of videos useful for video analysis, particularly in combination with convolutional neural networks (CNNs). A dynamic image encodes temporal data such as RGB or optical flow videos by using the concept of ‘rank pooling’. The idea is to learn a ranking machine that captures the temporal evolution of the data and to use the...

In this work a novel approach for color image segmentation using higher order entropy as a textural feature for determination of thresholds over a two dimensional image histogram is discussed. A similar approach is applied to achieve multi-level thresholding in both grayscale and color images. The paper discusses two methods of color image segmentation using RGB space as the standard processing...

We describe a new pushbroom hyperspectral imaging device that has no macro moving part. The main components of the proposed hyperspectral imager are a digital micromirror device (DMD), a CMOS image sensor with no filter as the spectral sensor, a CMOS color (RGB) image sensor as the auxiliary image sensor, and a diffraction grating. Using the image sensor pair, the device can simultaneously capt...

This paper addresses the problem of segmenting the image based on thresholding from its background by using combined approach of improved Bacterial foraging optimization approach and decomposed RGB planes. Three Thresholds are computed from three different RGB decomposed images. The summation of Threhold Values are applied on the image to perform segmentation. Image segmentation is the foundati...

Article history: Available online 8 February 2013 Feature extraction and representation is one of the most important issues in the contentbased image retrieval. In this paper, we propose a new content-based image retrieval technique using color and texture information, which achieves higher retrieval efficiency. Firstly, the image is transformed from RGB space to opponent chromaticity space, an...

Introduction People detection and tracking is an important and fundamental component for many robots, interactive systems and intelligent vehicles. Previous works have used cameras and 2D and 3D range finders for this task. In this paper, we present a 3D people detection and tracking approach using RGB-D data. Given the richness of the data, we learn target appearance models for the purpose of ...
