Exploration and Comparison of Image-Based Techniques for Strawberry Detection
… there are considerable differences in their color. Therefore, various color spaces are first studied in this work, and the most effective color components are used in detecting strawberries and differentiating mature and immature strawberries. </p> <p>In some color channels such as the R …

Example based texture synthesis and quantification of texture quality
… which uses a HSI (hue, saturation, intensity) color model in conjunction with the hybrid approach to improve the quality of the synthesized texture. Unlike the RGB (red, green, blue) color model, the HSI color model is more intuitive and closer to human perception. The hue, saturation and …

Color Models for Image Decomposition
… is a study of image decomposition techniques for color images. The decomposition of color images presents a new challenge since the choice of the color model has an effect on the resulting images. The color models are tested for both structure + noise and cartoon + texture decomposition. Numerical …

ENHANCEMENT AND RESTORATION OF DUST IMAGES
This dissertation focuses on the modeling of dust noise on ordinary images and formulating enhancement and restoration strategies to improve the quality of dusty images using a sequence of image processing steps. Analyses of images acquired in dusty environments show that the images tend to have …

Vision and Learning for Intelligent Human -Computer Interaction
… for visual motion analysis tasks: non-stationary color model adaptation for efficient localization, multiple visual cues integration for robust tracking, and learning motion models for capturing articulated hand motion. Besides, this dissertation describes a novel statistical learning method, the …

An evaluation of the manipulation of color in alternative color spaces
The amenability of various color-controlling algorithms to the real-time operator control of color stimuli was investigated. Mathematical models based on eight color spaces were employed: three uniform color spaces (L*u*v*, L*h*C*, and Y 2.2u' VI), a graphics algorithm (HLS), an opponent color …

Ocean color modeling: Parameterization and interpretation
<p>The ocean color as observed near the water surface is determined mainly by dissolved and particulate substances, known as "optically-active constituents," in the upper water column. The goal of ocean color modeling is to interpret an ocean color spectrum quantitatively to estimate the suite of …

Computer vision for plant and animal inventory
… edge and texture features. And then a K-means color model of the board is generated. Finally, the vegetation is segmented at pixel level using the color model. The proposed method is robust to lighting condition changes. (2) For tree counting in aerial images, we propose a novel method called …

Visualization of spatio-temporal data in two dimensional space
… information. Addition- ally, in this work, colors are used to represent the temporal data. Every data point has the time information which is converted into relevant color, based on the HSV color model. The variation in the time is represented by transition from one color to another and …

Object Detection and Collaboration in Heterogeneous Multi-Robot Systems
… with a depthcamera through OpenCV and the HSV color model; 2) we optimized a path planning and control system which would enable the Pioneer 3-DX to map its surrounding environment and navigate to target poses, as well as allow the Baxter to grasp, lift and drop the target objects using the …

REAL-TIME CLASSIFICATION OF CONTINUOUS GESTURES
… study include the use of adaptive background model with the combination of elliptical skin-color model, K-mean clustering, and local region Gaussian mixture to detect hand under complex background. The configuration that allows the system to respond promptly to the gesture when it starts or …

Contrast adaptation reveals increased organizational complexity of chromatic processing in the visual evoked potential
… and single-unit recordings suggest that color vision comprises multiple stages of processing. Post-receptoral channels appear to consist of both a stage of broadly-tuned opponent channels that compare cone signals, and a subsequent stage, which includes cells tuned to many different …
