Detecting shapes, lines and circles in images using Hough Transform technique with OpenCV in Python. Hough transform is a popular feature extraction technique to detect any shape within an image.
The Hough Transform stands as a widely employed technique in image processing to detect shapes, particularly simple ones such as lines, circles, and rectangles. When implemented in OpenCV, this method proves notably effective in identifying straight edges, and consequently, it excels in detecting rec...

When I have used so C++ code to detect, that no work. The code: #include <opencv2/opencv.hpp> #include <*fstream> std::vectorstd::string load_class_list() { std::vectorstd::string class_list; std::ifstream ifs("class.names"); ...
Search before asking I have searched the YOLOv8 issues and discussions and found no similar questions. Question I am trying to get mask of the detected object, having trouble getting the mask. I am using the converted tflite model in and...
Convolutional is the first step in training an AI application that relies on a computer vision model. In this phase, an image is scanned into the neural network so that the computer can precisely understand what it sees, down to each pixel. This allows it to detect and identify shapes, pat...
Besides leading the advancements in OCR, deep learning also created opportunities for exploration. Deep Reader, a workshop paper from the top CS conference ACCV*, is one example that utilizes neural networks to recognize shapes and formats extending beyond just words and symbols of a scanned docume...
