How could the softmax layer be used as one of the middle layers in a neural network and be backpropagated properly? Question: I am currently making my own machine learning library in c++ as an exercise to help me improve my coding skills and to improve my understanding of machine learning. I am currently making …
Inadequate transform produced by good homographic feature match Question: I’m trying to determine a method to rotate and translate a scanned 2D image to match it’s near-identical but lower-quality digital template. After running the code, I want the images to very closely align when overlaid, so that post-processing effects can be applied to the scan …
python opencv – filter contours by position Question: I use this code to find some blobs, and pick the biggest one. contours, hierarchy = cv2.findContours(th1, cv2.RETR_EXTERNAL, cv2.CHAIN_APPROX_NONE) if len(contours) != 0: c = max(contours, key=cv2.contourArea) Now, I would need to change this code in a way so it returns the contour that is in the …
How to compute Topk IoU in semantic segmentation using PyTorch? Question: Given outputs of a neural network outputs and a ground-truth label. outputs.shape = (N, C, H, W) and label.shape = (N, H ,W), where N is the batch size, C is the number of classes, H and W are crop sizes. Each element of …
Detect (and maybe decode) PDF417 barcodes using python Question: I am trying to detect the pdf417 barcode (2D barcode) from an image using python. I will be receiving images of IDs where there is a barcode in them but it might not always be straight. So I am looking for an effective way to DETECT …
What does it really mean real time object detection? Question: So here is the context. I created an script in python, YOLOv4, OpenCV, CUDA and CUDNN, for object detection and object tracking to count the objects in a video. I intend to use it in real time, but what real time really means? The video …
Error When Trying to Calculate FLOPS for Complex TF2 Keras Models Question: I want to calculate the FLOPS in the ML models used. I get an error when I tried to calculate for much complex models. I get this Error for Efficientnet Models: ValueError: Unknown layer: FixedDropout. Please ensure this object is passed to the …
Snake Algorithm (active contour) in python Question: Find contour on the right side of the chest image as indicated with red circle and by using Python and scikit-image package for the image below this is the image i have to process to make it like this result: the result must be like this Asked By: …
How can I identify objects inside the image using python opencv? Question: I’m trying to identify objects present inside the plane area as in below image for some automation image1 for this I tried finding the contours on masked image obtained using thresholding the hsv range of object border colors which is yellowish then I …
detect and count the number of star symbol in opencv-python Question: I need to count the occurrence of the stars at the right bottom corner in the image, I read this article Template Matching and used the following code to find the stars but My code doesn’t work for detecting the stars in the image. …
