Client Creation

With API Key

```java

import com.azure.ai.vision.imageanalysis.ImageAnalysisClient;

import com.azure.ai.vision.imageanalysis.ImageAnalysisClientBuilder;

import com.azure.core.credential.KeyCredential;

String endpoint = System.getenv("VISION_ENDPOINT");

String key = System.getenv("VISION_KEY");

ImageAnalysisClient client = new ImageAnalysisClientBuilder()

.endpoint(endpoint)

.credential(new KeyCredential(key))

.buildClient();

```

Async Client

```java

import com.azure.ai.vision.imageanalysis.ImageAnalysisAsyncClient;

ImageAnalysisAsyncClient asyncClient = new ImageAnalysisClientBuilder()

.endpoint(endpoint)

.credential(new KeyCredential(key))

.buildAsyncClient();

```

With DefaultAzureCredential

```java

import com.azure.identity.DefaultAzureCredentialBuilder;

ImageAnalysisClient client = new ImageAnalysisClientBuilder()

.endpoint(endpoint)

.credential(new DefaultAzureCredentialBuilder().build())

.buildClient();

```

Visual Features

| Feature | Description |

|---------|-------------|

| `CAPTION` | Generate human-readable image description |

| `DENSE_CAPTIONS` | Captions for up to 10 regions |

| `READ` | OCR - Extract text from images |

| `TAGS` | Content tags for objects, scenes, actions |

| `OBJECTS` | Detect objects with bounding boxes |

| `SMART_CROPS` | Smart thumbnail regions |

| `PEOPLE` | Detect people with locations |

Core Patterns

Generate Caption

```java

import com.azure.ai.vision.imageanalysis.models.*;

import com.azure.core.util.BinaryData;

import java.io.File;

import java.util.Arrays;

// From file

BinaryData imageData = BinaryData.fromFile(new File("image.jpg").toPath());

ImageAnalysisResult result = client.analyze(

imageData,

Arrays.asList(VisualFeatures.CAPTION),

new ImageAnalysisOptions().setGenderNeutralCaption(true));

System.out.printf("Caption: \"%s\" (confidence: %.4f)%n",

result.getCaption().getText(),

result.getCaption().getConfidence());

```

Generate Caption from URL

```java

ImageAnalysisResult result = client.analyzeFromUrl(

"https://example.com/image.jpg",

Arrays.asList(VisualFeatures.CAPTION),

new ImageAnalysisOptions().setGenderNeutralCaption(true));

System.out.printf("Caption: \"%s\"%n", result.getCaption().getText());

```

Extract Text (OCR)

```java

ImageAnalysisResult result = client.analyze(

BinaryData.fromFile(new File("document.jpg").toPath()),

Arrays.asList(VisualFeatures.READ),

null);

for (DetectedTextBlock block : result.getRead().getBlocks()) {

for (DetectedTextLine line : block.getLines()) {

System.out.printf("Line: '%s'%n", line.getText());

System.out.printf(" Bounding polygon: %s%n", line.getBoundingPolygon());

for (DetectedTextWord word : line.getWords()) {

System.out.printf(" Word: '%s' (confidence: %.4f)%n",

word.getText(),

word.getConfidence());

}

}

}

```

Detect Objects

```java

ImageAnalysisResult result = client.analyzeFromUrl(

imageUrl,

Arrays.asList(VisualFeatures.OBJECTS),

null);

for (DetectedObject obj : result.getObjects()) {

System.out.printf("Object: %s (confidence: %.4f)%n",

obj.getTags().get(0).getName(),

obj.getTags().get(0).getConfidence());

ImageBoundingBox box = obj.getBoundingBox();

System.out.printf(" Location: x=%d, y=%d, w=%d, h=%d%n",

box.getX(), box.getY(), box.getWidth(), box.getHeight());

}

```

Get Tags

```java

ImageAnalysisResult result = client.analyzeFromUrl(

imageUrl,

Arrays.asList(VisualFeatures.TAGS),

null);

for (DetectedTag t
