For real-time deep learning-based object detection on your CPU with OpenCV and Python, you may want to consider using the SSD. What would you like to do? It turns out that the parameters for the detectMultiScale is as important as the cascade itself to optimize the detection accuracy. I have trained SSD ResNet V1 model using Tensorflow 2 Object Detection API. It takes the entire image as an input and outputs class labels and class probabilities of objects present in that image. This way an additional .pbtxt file with TensorFlow graph will be created. Coke logos are usually seen in advertisements. One important thing to do here is preview these negative images and delete those who have coke logos in them. If there are no more objects to label, press ESC/ENTER key on opencv window, and press ENTER key on terminal when it asks you to label. I've started using OpenCV with a fair amount of success with a view to detecting different body parts (hands, arms, face, e.t.c). But before that we need to build an another annotation file for the resized object (logo) samples. You can change the detect object with your own training… github.com. ... static const std::string kWinName = " Deep learning object detection in OpenCV "; namedWindow (kWinName, WINDOW_NORMAL); int initialConf = (int)(confThreshold * 100); createTrackbar (" Confidence threshold, % ", kWinName, &initialConf, 99, callback); // Open a video file … Skip to content.

Lets begin. Since the logo comprises the entirety of image files extracted in the step above the annotation file contents will look like like this, This annotation file can be created quickly by the following python script, Once the annotation file is create, the following powershell command will create the .vec file from the positive samples. For example, a class label could be “dog” and the associated class probability could be 97%. It has the following parameters: the image to transform; the scale factor (1/255 to scale the pixel values to [0..1]); the size, here a 416x416 square image; the mean value (default=0); the option swapBR=True (since OpenCV uses BGR); A blob is a 4D numpy array object (images, channels, width, height).
