The Great AI Detective Games: YOLOv8 vs YOLOv11

Meet our two star detectives at the YOLO Detective Agency: the seasoned veteran Detective YOLOv8 (68M neural connections) and the efficient rookie Detective YOLOv11 (60M neural pathways). Today, they're facing their ultimate challenge: finding Waldo in a series of increasingly complex scenes.

Setting Up the Detective Agency

Before our detectives can begin their investigation, we need to set up their high-tech equipment. Here's how we equipped our agency:

!pip install roboflow

!pip install ultralytics

from roboflow import Roboflow

rf = Roboflow(api_key="YOUR_API_KEY")

project = rf.workspace("waldowally").project("waldo-qa5u7")

version = project.version(4)

dataset = version.download("yolov11")

Case File: Training Academy Records

Our AI Detective Academy maintains one of the most comprehensive "Spot Waldo" training programs in existence, powered by the elite Roboflow Training Database (codename: waldo-qa5u7). Both Detective YOLOv8 and Detective YOLOv11 underwent intensive training using 1,500 carefully documented crime scenes – 1,200 for basic training, 150 for advanced skill assessment, and 150 for final field qualification tests.

Each training scenario was meticulously mapped by our veteran spotters, who marked Waldo's exact coordinates using high-precision bounding boxes. The training grounds are incredibly diverse, ranging from packed beachfront operations and bustling urban surveillance to undercover carnival missions and treacherous ski slope stakeouts. Our seasoned instructors enhanced the training regime with advanced simulation techniques – rotating surveillance angles, adjusting light conditions, and varying observation distances – ensuring our detectives could spot their target under any circumstances.

This rigorous training program formed the backbone of our detective certification process, putting both YOLOv8 and YOLOv11 through identical data to ensure a fair evaluation of their crime-solving capabilities. After all, at the YOLO Detective Agency, we believe that great detectives aren't born – they're trained.

Training Our Detectives

Every good detective needs proper training. We put both our detectives through an intensive 20-epoch training program:

from ultralytics import YOLO

#Training Detective YOLOv11

model_v11 = YOLO("yolo11n.yaml")

model_v11.train(data="/content/waldo-4/data.yaml", epochs=20, imgsz=640)

#Training Detective YOLOv8

model_v8 = YOLO("yolov8n.yaml")

model_v8.train(data="/content/waldo-4/data.yaml", epochs=20, imgsz=640)

The Investigation Begins

Our detectives developed a sophisticated comparison technique to analyze each scene:

def compare_models_with_plots(image_path):

image = cv2.imread(image_path)

results_v11 = model_v11(image)

results_v8 = model_v8(image)

annotated_image_v11 = results_v11[0].plot()

annotated_image_v8 = results_v8[0].plot()

#Display predictions side by side

plt.figure(figsize=(15, 5))

plt.subplot(1, 2, 1)

plt.imshow(cv2.cvtColor(annotated_image_v11, cv2.COLOR_BGR2RGB))

plt.title("Detective YOLOv11's Analysis")

plt.axis('off')

plt.subplot(1, 2, 2)

plt.imshow(cv2.cvtColor(annotated_image_v8, cv2.COLOR_BGR2RGB))

plt.title("Detective YOLOv8's Analysis")

plt.axis('off')

plt.show()

Case Studies: The Battle of the Detectives

Case 1: The Crowded Beach

Detective YOLOv11 showcased its superior ability to spot smaller objects, while Detective YOLOv8 processed the scene with lightning speed. We measured their performance using our comprehensive analysis tool:

//?def compare_models_comprehensive(image_path): !! !! image = cv2.imread(image_path) !! !! #Measure Detective YOLOv11's speed !! !! start_time_v11 = time.time() !! !! results_v11 = model_v11(image) !! !! inference_time_v11 = time.time() - !! !! start_time_v11 !! !! #Measure Detective YOLOv8's speed !! !! start_time_v8 = time.time() !! !! results_v8 = model_v8(image) !! !! inference_time_v8 = time.time() - start_time_v8 !! !! print(f"Detective YOLOv11's Response Time: inference_time_v11:.4f seconds") !! !! print(f"Detective YOLOv8's Response Time: inference_time_v8:.4f seconds")//?

Performance Showdown

Our comprehensive investigation revealed:

Speed: Detective YOLOv8 maintained a slight edge with 50ms response time vs YOLOv11's 51ms
