Overlapping Objects issue in Counting Insects with OpenCV

I'm trying to count the number of a group of crickets(insect). I will use the image processing method, by openCV library. This will provide more accuracy practice, when the farmers sell their crickets. The photo was taken from a smartphone. Unfortunately, the results were not as expected. Since, most crickets overlap on each other, my code couldn't separate them into individual, resulting in an incorrect count.

what method that I should apply to this issue? Is there something wrong with my code?

Crickets image

And here is my code.

import cv2
import numpy as np

img = cv2.imread("c1.jpg",1)

roi=img[0:1500,0:1100]  
gray = cv2.cvtColor(roi,cv2.COLOR_BGR2GRAY)
gray_blur=cv2.GaussianBlur(gray,(15,15),0)
thresh = cv2.adaptiveThreshold(gray_blur,255,cv2.ADAPTIVE_THRESH_GAUSSIAN_C,cv2.THRESH_BINARY_INV,11,1)
kernel=np.ones((1,1),np.uint8)
closing=cv2.morphologyEx(thresh,cv2.MORPH_CLOSE,kernel,iterations=10)

result_img=closing.copy()
contours,hierachy=cv2.findContours(result_img,cv2.RETR_EXTERNAL,cv2.CHAIN_APPROX_SIMPLE)
counter=0
for cnt in contours:
    area = cv2.contourArea(cnt)
    if area <  150  :
    #if area<  300 :
        continue
    counter+=1
    ellipse = cv2.fitEllipse(cnt)
    cv2.ellipse(roi,ellipse,(0,255,0),1)
        
  
cv2.putText(roi,"Crickets="+str(counter),(100,70),cv2.FONT_HERSHEY_SIMPLEX,1,(255,0,0),1,cv2.LINE_AA)
cv2.imshow('ImageOfCrickets',roi)
#cv2.imshow('ImageOfGray',gray)
#cv2.imshow('ImageOfGray_blur',gray_blur)
#cv2.imshow('ImageOfThreshold',thresh)
#cv2.imshow('ImageOfMorphology',closing)

print('Crickets = '+ str(counter))     

cv2.waitKey(0)
cv2.destroyAllWindows()

Now, I'm using closing morphology and Contours Hierarchy for ellipse shape method.

How to extract css as a separate .css file in Vite?

In webpack it is possible to generate output in such a way:

• 1 file with bundled js code
• 1 file with bundled css

This is part of the webpack config, that results in such output:

const MiniCssExtractPlugin = require('mini-css-extract-plugin')

...

plugins: [
  new MiniCssExtractPlugin({
    filename: 'assets/css/styles.css',
    chunkFilename: '[id].css',
  }),
  ...
],

...

{
  test: /\.css$/,
  use: [
    {
      loader: MiniCssExtractPlugin.loader,
    },
    {
      loader: 'css-loader',
    },
  ],
},

...

How to achieve this with vite?

The vite templates by default generate config, where js and css are bundled into a single file and css is injected at runtime.

Failed to fetch the job titles from indeed using the requests module

I'm trying to grab job titles from the search result of a webpage, indeed.com, using the requests module. Here is the link to that webpage where I wish to fetch the job titles.

The following is how I've already tried:

import requests
from bs4 import BeautifulSoup

link = "https://www.indeed.com/jobs"
params={
    'q': 'motorcycle mechanic',
    'l': 'New York, NY'
}
headers = {
    'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/103.0.0.0 Safari/537.36',
}
def get_job_titles(url):
    res = requests.get(url,params=params,headers=headers)
    soup = BeautifulSoup(res.text,"lxml")
    link_list = []
    for item in soup.select("#mosaic-jobResults td.resultContent h2 > a > span[id^='jobTitle']"):
        link_list.append(item.get("href"))
    return link_list

if __name__ == '__main__':
    for title in get_job_titles(link):
        print(title)

When I run the script, I always get status 403. How can I get the job titles from that webpage using the requests module?
