### Plant detection and counting from highresolution RGB ...

· Automated detection of individual plants in images is a key step to estimate this density. To develop and evaluate dedicated processing technics, high resolution RGB images were acquired from UAVs during several years and experiments over maize, sugar beet and sunflower crops at early stages. A total of 16247 plants have been labelled interactively. We compared the performances of …

### A Shadow Detection and Removal from a Single Image Using ...

To detect shadow initially the RGB image is converted to an LAB equivalent image. The LAB color space has three channels where L is the Lightness channel, A and B are the two color channels. The L channel has values ranging from 0 up to 100, which corresponds to different shades from black to white. The A channel has values ranging from −128 up to +127 and gives the red to green ratio. The B ...

can be used to detect dry, ozonerich stratospheric air associated with PV anomalies. These same techniques also can be applied to other satellite instruments that observe at similar wavelengths (EUMETSAT 2012a, b). RGB imagery can be produced from the National Aeronautics and Space Administration (NASA) Moderate Resolution Imaging Spectroradiometer (MODIS) aboard the Terra …

### RGBD Object Recognition and Grasp Detection Using ...

· This paper presents an efficient framework to perform recognition and grasp detection of objects from RGBD images of real scenes. The framework uses a novel architecture of hierarchical cascaded forests, in which objectclass and grasppose probabilities are computed at different levels of an image hierarchy (, patch and object levels) and fused to infer the class and the grasp of unseen ...

### [] RGBD imagebased Object Detection: from ...

· Object detection from RGB images is a longstanding problem in image processing and computer vision. It has applications in various domains including robotics, surveillance, humancomputer interaction, and medical diagnosis.

### Optimizing human model reconstruction from RGBD images ...

· Skin detection of RGBD images helps to tightly constrain the skin parts of human body in template fitting step in order to get more precise and lifelike human model. We propose a robust skin detection method that is not affected by clothing pattern and background. Experiments demonstrate the effectiveness of our method. Introduction. With the booming of 3D movies and virtual fitting room, it ...

### Shadow Detection and Removal from a Single Image Using LAB ...

remove shadows from a single RGB image. A shadow detection method is selected on the basis of the mean value of RGB image in A and B planes of LAB equivalent of the image. The shadow removal is done by multiplying the shadow region by a constant. Shadow edge correction is done to reduce the errors due to diffusion in the shadow boundary. Keywords: Shadow detection, shadow removal, LAB …

### 006 CNN Convolution On RGB Images | Master Data Science

· For example, if we want to detect features, not just in a grayscale image, but in an RGB image. 2D (or a grayscale) image and 3D (or a RGB) image. Instead of a $$6 \times 6$$ image, an RGB image could be $$6 \times 6 \times 3$$ where the $$3$$ here corresponds to the $$3$$ color channels. We can think of this as a stack of three $$6 \times 6$$ images. In order to detect edges or some ...

### Improving Edge Detection in RGB Images by Adding NIR Channel

for detecting edges in images from the visible spectrum (, RGB images). The visible spectrum (VIS) ranges from 400nm to 700nm. Just after the visible spectrum we have the Near Infrared (NIR) spectral band, which cover from 700nm till 1100nm. The NIR spectral band could be added to visible spectrum (VIS) images to improve image processing issues such as restoration [11], enhancement [12 ...

### Object Detection with PyTorch and Detectron2

Object Detection with PyTorch and Detectron2. In this post, we will show you how to train Detectron2 on Gradient to detect custom objects ie Flowers on Gradient. We will show you how to label custom dataset and how to retrain your model. After we train it we will try …

### A Color Edge Detection Algorithm in RGB Color Space | IEEE ...

· A Color Edge Detection Algorithm in RGB Color Space Abstract: Edge detection is one of the most commonly used operations in image processing and pattern recognition, the reason for this is that edges form the outline of an object. An edge is the boundary between an object and the background, and indicates the boundary between overlapping objects. This means that if the edges in an image …

### Detecting Humans in RGBD Data with CNNs

CNNs have also been applied in RGBD images for human detection, such as [7, 8]. In [7] however, depth is not included in the classi cation. Mees et al. [8] develop a mixture of CNNs to extract features independently from di erent modalities including color, depth and motion, and use a gating network to fuse them Figure 1: Overview of our human detection system. for further classi cation ...

### Learning Rich Features from RGBD Images for Object ...

Object detection in RGBD images [20,22,25,35,38], in contrast, focusses on instances, but the typical output is a bounding box. As Hariharan et al. [19] observe, neither of these tasks produces a compelling output representation. It is not enough for a robot to know that there is a mass of ‘bottle’ pixels in the image. Likewise, a roughly localized bounding box of an individual bottle ...
