Question

Please show me the code that will let me change the confidence threshold of YOLOv8 in this code. Currently using webcam as my camera feed for real-time object detection

from ultralytics import YOLO

# Load the custom YOLOv8 model

 frame = cv2.cvtColor(frame, cv2.COLOR_BGR2RGB)

 results = model(frame)

 app.after(10, detect)

 else:

app = tk.Tk()

app.title("YOLOv8 Inference")

clsBtn.pack()

detect()

2. Use the slider's value to set the confidence threshold for the YOLOv8 model.

import cv2

model = YOLO('best.pt')

# Function to update the confidence threshold based on the slider's value

def detect():

    success, frame = cap.read()

        photo = ImageTk.PhotoImage(image=Image.fromarray(annotated_frame))

        canvas.create_image(0, 0, anchor=tk.NW, image=photo)

# Function to close the application

def close():

# Set up the Tkinter application

app = tk.Tk()

canvas = tk.Canvas(app, width=640, height=480)

canvas.pack()

# Set up the close button

clsBtn = tk.Button(app, text="Close", command=close)

app.mainloop()
