Face detection box does not appear on the local server. (Django)
It is a mask detection code (camera.py) using Yolo model. I tried to implement this on django server. The video appeared on the screen by webcam without any problems. However, the face detection box is not showing up. I tried using VideoStream instead of VideoCapture, but the results were the same. And when I printed out the jpeg, I checked that it came out properly. What's the problem?... import cv2,os,urllib.request import numpy as np from django.conf import settings # from imutils.video import VideoStream import imutils # load our serialized face detector model from disk os.chdir(r'C:/Users/rjsgh/OneDrive/Desktop/Mask_Detection/warming_up_project/streamapp') weightsPath = "./face_detector/yolov4-tiny-obj_best.weights" cfgPath = "./face_detector/yolov4-tiny-obj.cfg" yoloNet = cv2.dnn.readNet(weightsPath, cfgPath) layer_names = yoloNet.getLayerNames() output_layers = [layer_names[i[0] - 1] for i in yoloNet.getUnconnectedOutLayers()] LABELS = ["Mask", "No Mask"] COLORS = [(0,255,0), (0,0,255)] class yoloDetect(object): def __init__(self): self.vs = cv2.VideoCapture(0) def __del__(self): self.vs.release() cv2.destroyAllWindows() def detect_mask(self, frame): (h,w) = frame.shape[:2] blob = cv2.dnn.blobFromImage(frame, 1/255.0, (416, 416), swapRB=True, crop=False) yoloNet.setInput(blob) layerOutputs = yoloNet.forward(output_layers) class_ids = [] cofidences = [] boxes = [] for output in layerOutputs : for detection in output : scores = detection[5:] class_id = np.argmax(scores) confidence = scores[class_id] if confidence > 0.5 : box = detection[:4] * np.array([w,h,w,h]) (center_x, center_y, width, height) = box.astype("int") x … -
how can I download image with different sizes in jquery or python django?
I have an image which is displayed to user. User can select the size of image which he/she want to download. How can I do so. I don't want to store the different sizes of image. I want to create a function with parameter specifying the size which will be called when the user click the download button. From that function the image should get downloaded (without changing the actual file size and should not create a new file or if created should not get stored anywhere). If it is possible to do such thing in jquery will be appreciated, so that there will be no need to send request to backend, if not then in python django. -

Integrating Django and React
So guys, I was trying to integrate Django and React. I have seen different ways of doing that. The method that I tried using is the one where there are two different folders frontend and backend. The backend has my Django project and the frontend has my React app created by the create-react-app command. I could fetch data from the API using axios. What has been difficult for me is the authentication part. It uses actions and reducers for that. It also uses tokens and other stuffs too. I found a tutorial which explains this clearly. But it's kindda outdated. I was following it step by step until it reached the authentication part and it didn't work, which made it more complicated for me to understand it. So I was looking for another approach or guide that I can follow for the integration of Django and React - specially the authentication part. Thank you! -
