The computer vision task of finding and identifying objects in an image or video sequence

The computer vision task of finding and identifying objects in an image or video sequence is often conducted consistent with one of two approaches:

  • Appearance-based methods

    • Use example images (called templates or exemplars) of the objects to perform recognition

    • Objects look different under varying conditions:

  • Feature-based method

    • a search is used to find feasible matches between object features and image features.

    • the primary constraint is that a single position of the object must account for all of the feasible matches.

Does a free API for a Augmented reality service exist?

Currently I am trying to create an app for iPhone which is capable of recognizing the objects on an image such as car, bus, building, bridge, human, etc, and label as object name with the help of Internet. Is there any free service which provide…

OpenTLD, how is it different from other object detection methods?

For those that have heard of OpenTLD, how does it alternate between tracking different objects? It can only track one object at a time, but if I had two or more objects trained in the same video feed, how does OpenTLD decide what to track? In all…

Bad results using OpenCV with Yolov5 comparing with pure Yolov5

I'm tryting to recognize lego bricks from video cam using opencv. It performs extremely bad comparing with just running detect.py in Yolov5. Thus I made some experiments about just recognizing images, and I found using openCV still performs…

Ideas for extracting features of an object using keypoints of image

I'll be appreciated if you help me to create a feature vector of an simple object using keypoints. For now, I use ETH-80 dataset, objects have an almost blue background and pictures are took from different views. Like this: After creating a feature…

Object & Shape Recognition from webcam

I need to create an application to get input from a webcam or camera connected to a computer and detect certain 3d objects. I could do this from a .3ds file or something else? I'm not quite sure. I am pretty sure it is possible with flash as3? I…

TensorFlow object detection results showing 'N/A'

I'm training a deep learning model for custom object detection using TensorFlow 1.15 on Google colab. I'm using ssd_mobilenet_v2_quantized_coco. After some training (20k steps) with losses 1.5 ~ 2.5, I generated the inference graph and checked the…

Pytorch/YOLOv5 - Compare detected Object if it's the same

I am trying to use Pytorch and YOLOv5 to detect objects in multiple images and count them. My problem now is that if I have for example a frame rate of 15fps, the same objects can be recognized in the image, but they were only recognized for example…

How could one use OpenCV to count isolated white spots in below image for each circle in the circle grid?

I can detect the spots using houghcircles function in opencv: circles = cv2.HoughCircles(cimg,cv2.HOUGH_GRADIENT,1,0.1,param1=50,param2=30,minRadius=1,maxRadius=40) This can be further improved with image segmentation and watershed I guess for…

object recognition algorithm that can generate Bounding box along the object

I'm working on a dataset which contains biscuits and soaps in which most of the cases biscuits/soaps are rotated. For training images, I'm having a white background in the image, so I can generate a Bounding box along with the object by thresholding…
