I need to implement a multi-label image classification model in PyTorch. However my data is not balanced, so I used the WeightedRandomSampler in PyTorch to create a custom dataloader. But when I it...

Long story short: How to prepare data for lstm object detection retraining of the tensorflow master github implementation. Long story: Hi all, I recently found implementation a lstm object detec...

I have one mask: According to this method After coding, I get the result as below: Since this is a new circular shape rather than a straight line, measuring the width using the rotation method ab...

I am trying to import PySpin in Visual Studio to be able to work with Flir's camera but every time I encounter this: "No module named 'PySpin'" And when I try the Pip install PySpin, no...

I am a newbie and having difficulty on resolving this issue. What I am trying to do is run the sample code from face_recognition using a webcam. Both of the two example doesn't work on me and keeps...

Imagine, you have different OCR tools to read text from images but none of them gives you a 100% accurate output. Combined however, the result could come very close to the ground truth - What...

How can I find multiple objects of one type on one image. I use ORB feature finder and brute force matcher (opencv = 3.2.0). My source code: import numpy as np import cv2 from matplotlib import p...

I am implementing a Harris corner detector for educational purposes but I'm stuck at the harris response part. Basically, what I am doing, is: Compute image intensity gradients in x- and y-direct...

I was reading this paper "Self-Invertible 2D Log-Gabor Wavelets" it defines 2D log gabor filter as such: The paper also states that the filter only covers one side of the frequency space and sh...

Is there an Edge Detection Method that performs significantly better than the Canny Edge Detector ??

I'm trying to access my laptop's built-in infrared webcam (intended for windows hello) in a Python project. I can access the normal RGB camera quite easily using the VideoCapture class from OpenCV,...

So normally and very inefficiently min/max filter is implemented by using four for loops. for( index1 < dy ) { // y loop for( index2 < dx ) { // x loop for( index3 < StructuringElement....

In the pinhole camera model there is only one focal length which is between the principal point and the camera center. However, after calculating the camera's intrinsic parameters, the matrix cont...

how to convert a single COCO JSON annotation file into a YOLO darknet format?? like below each individual image has separate filename.txt file

l have a set of images of different sizes (45,50,3), (69,34,3), (34,98,3). l want to add padding to these images as follows: Take the max width and length of the whole images then put the image in...

I have built a dataset to train YOLOv4 and I have all the labels in YOLO format (I used LabelImg). Now I want to train SSD with the same dataset and therefore I need the labels in the PASCAL VOC fo...

I am reading up on homographies and i have seen some places that it says that the homography is defined "up to a scale factor" what does this mean? Is there an upper limit for scaling the homograph...

I know about Gaussian, variance, and image blurring, and I think that I understood the concept of variance at Gaussian blur, but still I am not 100% sure. I just want to know the role of sigma or v...

I've been trying to experiment with Region Based: Dice Loss but there have been a lot of variations on the internet to a varying degree that I could not find two identical implementations. The prob...

I'm trying to make a currency recognition model and I did so using a dataset on kaggle and colab using yolov5 and I exactly carried out the steps explained on yolov5 github. At the end, I downloade...

Please suggest a new approach or at least a method to make any of these robust enough to detect at good rate I have some images (mostly taken from computer screen) where some kind of flash from cam...

I am currently trying to implement K-FOLD cross validation in classification using sklearn in python. I understand the basic concept behind K-FOLD and cross validation. However, I dont understand w...

I am trying to load this semantic segmentation model from HF using the following code: from transformers import pipeline model = pipeline("image-segmentation", model="Carve/u2net-un...

I have an image of a coffee can with an orange lid position of which I want to find. Here is it . gcolor2 utility shows HSV at the center of the lid to be (22, 59, 100). The question is how to cho...

When people try to solve the task of semantic segmentation with CNN's they usually use a softmax-crossentropy loss during training (see Fully conv. - Long). But when it comes to comparing the perfo...
