response.choices[0].message.content

In the above code, we are passing the url of the image along with the prompt to describe the image in the url. Below is the image which we are passing.

Output

Image Analysis with Local Images

api_key = "Enter your key"
def encode_image(image_path):
 with open(image_path, "rb") as image_file:
   return base64.b64encode(image_file.read()).decode('utf-8')


# Path to your image
image_path = "/content/cat.jpeg"


# Getting the base64 string
base64_image = encode_image(image_path)


headers = {
 "Content-Type": "application/json",
 "Authorization": f"Bearer {api_key}"
}


payload = {
 "model": "gpt-4o",
 "messages": [
   {
     "role": "user",
     "content": [
       {
         "type": "text",

         "image_url": {
           "url": f"data:image/jpeg;base64,{base64_image}"
         }
       }
     ]
   }
 ],
 "max_tokens": 300
}


response = requests.post("https://api.openai.com/v1/chat/completions", headers=headers, json=payload)

In the above, we pass the image of the cat below, showing the mode to describe the image. 

Output

print(response.json()["choices"][0]["message"]["content"])

Passing multiple images

from openai import OpenAI


client = OpenAI(api_key='Enter your Key')
response = client.chat.completions.create(
 model="gpt-4o",
 messages=[
   {
     "role": "user",
     "content": [
       {
         "type": "text",
         "text": "Tell me the difference and similarities of these two images",
       },
       {
         "type": "image_url",
         "image_url": {
           "url": "https://upload.wikimedia.org/wikipedia/commons/thumb/3/3f/Walking_tiger_female.jpg/1920px-Walking_tiger_female.jpg",
         },
       },
       {
         "type": "image_url",
         "image_url": {
           "url": "https://upload.wikimedia.org/wikipedia/commons/7/73/Lion_waiting_in_Namibia.jpg",
         },
       },
     ],
   }
 ],
 max_tokens=300,
)

In the above code, we pass in multiple images using their URLs. Below are the images that we are passing.

We prompted the comparison of these two images to find their similarities and differences. 

Output

print(response.choices[0].message.content)

Image Generation

One of ChatGPT-4 Vision’s most intriguing features is its capacity to produce visuals from textual descriptions. This creates new opportunities for design, content production, and creative applications.

Key Features

• Text-to-Image Generation: the process of producing visuals from comprehensive written descriptions. This has applications in the entertainment, education, and advertising sectors.
• Style Transfer: Transferring an image’s style to another is known as style transfer. This helps create material on social networking, graphic design, and digital art.
• Image editing is the process of altering preexisting images in response to text instructions. It can improve activities involving manipulation, restoration, and photo editing.

Example Use Case

Designers in the fashion business can use ChatGPT-4 Vision to create visuals of garment designs from written descriptions. This can speed up the design process, enable virtual prototyping, and improve idea exchange.

Implementation of Image Generation

The Images API provides three methods for interacting with images:

• Creating images from scratch based on a text prompt (DALL- E 3 and DALL – E 2)
• Creating variations of an existing image (DALL – E 2 only)

Creating Images using prompt

from openai import OpenAI
client = OpenAI(api_key='Enter your key')


response = client.images.generate(
 model="dall-e-3",
 prompt="a white siamese cat",
 size="1024x1024",
 quality="standard",
 n=1,
)


image_url = response.data[0].url

We have prompted the DALL-E 3 mode to create a white Siamese cat image. 

# Download the image
image_response = requests.get(image_url)

# Open the image using PIL
image = Image.open(BytesIO(image_response.content))

# Display the image
display(image)

Output

Image variation of an existing image

from openai import OpenAI
client = OpenAI(api_key='Enter your key')


response = client.images.create_variation(
 model="dall-e-2",
 image=open("/content/spider_man.png", "rb"),
 n=1,
 size="1024x1024"
)


image_url = response.data[0].url

We are using DALL-E 2 to create a variation of the existing image. We are passing the below image to the API to create a variation. 

# Download the image
image_response = requests.get(image_url)

# Open the image using PIL
image = Image.open(BytesIO(image_response.content))

# Display the image
display(image)

Output

We can see that the model has created a variation of our image. 

Video Analysis

Actionable insights can be extracted through the processing of video streams, expanding the scope of picture analysis into the temporal domain. Action identification, motion detection, and event detection in videos are among the functions that ChatGPT-4 Vision is capable of.

Key Features

• Action Recognition: Recognising particular movements made by participants in a video. This can be used in surveillance, human-computer interaction, and sports analytics.
• Motion detection: This can benefit animation, video surveillance, and traffic monitoring applications.
• Event detection: It is the process of locating important occurrences in a video. It can be applied in various fields, including security for incident detection, entertainment for automated highlight generation, and healthcare for patient activity monitoring.

Example Use case

ChatGPT-4 Vision can analyze game videos in sports analytics to identify player activities like basketball dribbling, shooting, and passing. This data can provide insights into player performance, game strategy, and training efficacy.

                       "text": "Describe me this image"
                   },
                   {
                       "type": "image_url",
                       "image_url": {
                           "url": f"data:image/jpeg;base64,{base64_image}"
                       }
                   }
               ]
           }
       ],
       "max_tokens": 300
   }


   response = requests.post("https://api.openai.com/v1/chat/completions", headers=headers, json=payload)
   return response.json()


def analyze_video(video_path, api_key, frame_interval=30):
   frames = extract_frames(video_path, frame_interval)
   analysis_results = []


   for frame in frames:
       result = analyze_frame(frame, api_key)
       analysis_results.append(result)


   return analysis_results


# Path to your video
video_path = "/content/Kendall_Jenner.mp4"
api_key = "Enter your key"


# Analyze the video
results = analyze_video(video_path, api_key)


for result in results:
   print(result['choices'][0]["message"]["content"])

In the above code, we are taking a video of a celebrity doing a ramp walk; we are taking our frames at an interval of 30 and making an API call to know the description.
