<model_size> with the desired LLaVA model parameter size (e.g., 7b, 13b, or 34b)../path/to/your/image.jpg to the relative or absolute path of your image file.For example, to describe an image named art.jpg using the 13B model, your command would look like this:
ollama run llava:13b "describe this image: ./art.jpg"
View the Results: After executing the command, the model will process the image and output a description. This description will appear directly in your terminal, providing insights into the content and context of the image.
Experiment with Different Commands: Beyond simple descriptions, you can experiment with various prompts to explore other aspects of the image, such as asking about the mood, identifying specific elements, or even generating creative interpretations.
By following these steps and tips, you can harness the power of Ollama Vision and LLaVA models directly from your command line, opening up a world of possibilities for image analysis and interpretation. Whether you're conducting research, developing applications, or creating art, these tools provide a new dimension of interaction with digital imagery.
Using Python to interact with Ollama Vision's LLaVA models involves leveraging the ollama.chat function. This powerful feature allows you to send an image for analysis and retrieve insightful descriptions. Here's a sample Python script that demonstrates how to accomplish this:
import ollama
# Initialize the Ollama client
ollama_client = ollama.OllamaClient()
# Define the path to your image
image_path = './path/to/your/image.jpg'
# Prepare the message to send to the LLaVA model
message = {
'role': 'user',
'content': 'Describe this image:',
'images': [image_path]
}
# Use the ollama.chat function to send the image and retrieve the description
response = ollama_client.chat(
model="llava:13b", # Specify the desired LLaVA model size
messages=[message]
)
# Print the model's description of the image
print(response['messages'][-1]['content'])
In this script:
./path/to/your/image.jpg with the actual path to your image file.llava:13b to the specific LLaVA model size you intend to use (7b, 13b, or 34b).Achieving similar functionality in JavaScript requires handling asynchronous operations with await. The following snippet shows how to use the ollama.chat method in a JavaScript environment to analyze an image and receive a description:
import ollama from 'ollama';
async function describeImage(imagePath) {
// Initialize the Ollama client
const ollamaClient = new ollama.OllamaClient();
// Prepare the message to send to the LLaVA model
const message = {
role: 'user',
content: 'Describe this image:',
images: [imagePath]
};
// Use the ollama.chat function to send the image and retrieve the description
const response = await ollamaClient.chat({
model: "llava:13b", // Specify the desired LLaVA model size
messages: [message]
});
// Log the model's description of the image
console.log(response.messages[response.messages.length - 1].content);
}
// Replace './path/to/your/image.jpg' with the path to your image file
describeImage('./path/to/your/image.jpg');
In this JavaScript example:
'./path/to/your/image.jpg' with the actual path to your image file."llava:13b" to select the LLaVA model size you wish to use (7b, 13b, or 34b).These examples in Python and JavaScript demonstrate how straightforward it is to integrate LLaVA models into your projects, enabling advanced image analysis capabilities with minimal code. Whether you're developing a web application, conducting research, or creating digital art, these snippets serve as a foundation for exploring the vast potential of Ollama Vision.
When you venture beyond basic image descriptions with Ollama Vision's LLaVA models, you unlock a realm of advanced capabilities such as object detection and text recognition within images. These functionalities are invaluable for a wide range of applications, from developing interactive AI-driven tools to conducting detailed visual research.
Object detection involves identifying and classifying individual items within an image. This can range from recognizing everyday objects like furniture and vehicles to more specialized items such as wildlife species or technical components.
Sample Command:
ollama run llava:13b "identify and classify objects in this image: ./cityscape.jpg"
Expected Output:
The model might return a detailed list of identified objects, such as "traffic lights, pedestrian crossing signs, cars, bicycles, and trees," along with possible classifications or characteristics, such as "sedan, SUV, deciduous tree."
Text recognition, or Optical Character Recognition (OCR), allows the model to detect and interpret text embedded in images. This can be particularly useful for digitizing written documents, extracting information from signage in images, or analyzing graphical content that includes text.
Sample Command:
ollama run llava:34b "extract and interpret text from this image: ./handwritten_notes.jpg"
Expected Output:
The model could output the transcribed text, possibly noting its confidence level or highlighting areas of uncertainty. For handwritten notes, it might also provide context or interpretation based on the surrounding content.
The LLaVA models can process images provided in different formats, catering to the flexibility required in various development environments.
CLI: In the command line interface, images are typically provided via file paths directly in the command, as shown in the sample commands above. This method is straightforward and effective for scripts and batch processing.
Python and JavaScript: In programming environments like Python and JavaScript, images can be provided as base64-encoded strings. This approach is particularly useful when dealing with images sourced from the web or generated within the application.
Python Example:
import base64
# Function to encode image file to base64
def encode_image_to_base64(image_path):
with open(image_path, "rb") as image_file:
return base64.b64encode(image_file.read()).decode('utf-8')
image_base64 = encode_image_to_base64('./path/to/your/image.jpg')
JavaScript Example:
const fs = require('fs');
// Function to encode image file to base64
function encodeImageToBase64(imagePath) {
return fs.readFileSync(imagePath, { encoding: 'base64' });
}
const imageBase64 = encodeImageToBase64('./path/to/your/image.jpg');
In these examples, the image file is read and converted to a base64-encoded string, which can then be included in the message payload sent to the LLaVA model for analysis.
These advanced use cases and methods of providing images open up a wide range of possibilities for integrating Ollama Vision into your projects, enabling sophisticated visual analysis and interaction within your applications.
