stitching image adopts equirectangular projection (ERP). algorithms are optimized by AVX512 instruction, GLES and Vulkan. stitching quality tuning supports OpenCV fisheye camera calibration parameters. Automotive surround view (360-degree) stitching (OpenCL/CPU/GLES) ...
We determined that MediaPipe Holistic could locate pose keypoints in a thermal image. After lengthy experimentation with different sets of pose keypoints, we chose to create two least-squares homographies (planar transformation matrices) with the OpenCV [52] function findHomography(): We then use ...
Our system architecture is divided into two steps, namely, data preprocessing and eye blink detection, as described inFigure 3. In the data preprocessing step, the video labeling procedure using Eyeblink Annotator 3.0 by Andrej Fogelton [46] is shown inFigure 4. OpenCV version 2.4.6 is utiliz...
The open-source computer vision software OpenCV is used to resize the image to match it with the network model’s input. The original collected images were pretreated. The image with a pixel resolution of 2048 × 2048 was cropped to the image with a pixel resolution of 512 × 512, which ...
* Fix OpenCV Fisheye camera model to exactly match OpenCV specifications --- COLMAP 3.2 (9/2/2017) === --- * Fully automatic cross-platform build script (Windows, Mac, Linux) * Add multi-GPU feature extraction if multiple CUDA devices are available * Configurable dimension and data type...
market, yet. But showing you just the point of view of the general consumer is surely not fair, so I’ll add some lines from the point of view of a user that knows a bit about augmented reality and that has also tried in the past to develop an AR framework himself ...

For the RF and SVM models, the OpenCV 3.4.2 [93], scikit-learn 0.24.2, and scikit-image 0.18.1 [94] Python 3.7.0 libraries were used to implement machine learning. Using the methods of Canny, Robert, Sobel, Scharr, and Prewitt, edge-based features were extracted as grayscale images...
Among the methods for obtaining a binary image, one can single out, for example, thresholding or selecting an object by color. The OpenCV library contains convenient methods for detecting and manipulating image edges. The find contours function is used to find contours in a binary image. This ...
Table 8.Hierarchical multiclassifier: 10-fold cross-validation accuracy percentage obtained selecting each sensor image as the root node. 5.4. Results Obtained by HOG To obtain HOG-based proposals, we use the GPUimplementation in OpenCV. The detector can process 640 × 480 images in 5–10 Hz....
