A collection of easy-to-use image / video filters.

# How to use

### Setting Up

1, Add SemanticImage to your project as Swift Package with Swift Package Manager. 
   Or just drag SemanticImage.swift to your project.

2, Import and initialize SemanticImage

```swift
import SemanticImage
```

```swift
let semanticImage = SemanticImage()
```

**Requires iOS 14 or above**

# Filter Collection

## Image

### Get Person Mask

```swift
let maskImage:UIImage? = semanticImage.personMaskImage(uiImage: yourUIImage)
```

### Swap the background of a person

```swift
let swappedImage:UIImage? = semanticImage.swapBackgroundOfPerson(personUIImage: yourUIImage, backgroundUIImage: yourBackgroundUIImage)
```

### Blur the backgrond of a person

```swift
let blurredPersonImage:UIImage? = semanticImage.personBlur(uiImage:UIImage, intensity:Float)
// Blur intensity: 0~100 
```

### Get a prominent object mask

```swift
let prominentMaskImage:UIImage? = semanticImage.saliencyMask(uiImage:image)
```

### Swap the background of the prominent object

```swift
let backgroundSwapImage:UIImage? = semanticImage.saliencyBlend(objectUIImage: image, backgroundUIImage: bgImage)
```

### Crop a face rectangle

```swift
let faceImage:UIImage? = semanticImage.faceRectangle(uiImage: image)
```

### Crop a body rectangle

```swift
let bodyImage:UIImage? = semanticImage.humanRectangle(uiImage: image)
```

### Crop face rectangles

```swift
let faceImages:[UIImage] = semanticImage.faceRectangles(uiImage: image)
```

### Crop body rectangles

```swift
let bodyImages:[UIImage] = semanticImage.humanRectangles(uiImage: image)
```

### Crop an animal(Cat/Dog) rectangle

```swift
let animalImage:UIImage? = semanticImage.animalRectangle(uiImage: image)
```

### Crop multiple animal(Cat/Dog) rectangles

```swift
let animalImages:[UIImage] = semanticImage.animalRectangles(uiImage: image)
```

### Crop and warp document

```swift
let documentImage:UIImage? = semanticImage.getDocumentImage(image: image)
```

## Video

### Apply CIFilter to Video

```swift
guard let ciFilter = CIFilter(name: "CIEdgeWork", parameters: [kCIInputRadiusKey:3.0]) else { return }
semanticImage.ciFilterVideo(videoURL: url, ciFilter: ciFilter, { err, processedURL in
    // Handle processedURL in here.
})
// This process takes about the same time as the video playback time.
```

### Add virtual background of the person video

```swift
semanticImage.swapBackgroundOfPersonVideo(videoURL: url, backgroundUIImage: uiImage, { err, processedURL in
    // Handle processedURL in here.
})
    // This process takes about the same time as the video playback time.
```

### Add virtual background of the salient object video

```swift
semanticImage.swapBGOfSalientObjectVideo(videoURL: url, backgroundUIImage: uiImage, { err, processedURL in
    // Handle processedURL in here.
})
    // This process takes about the same time as the video playback time.
```

### Process video

```swift
semanticImage.applyProcessingOnVideo(videoURL: url, { ciImage in
    // Write the processing of ciImage (i.e. video frame) here.
    return newImage
}, {  err, editedURL in
   // The processed video URL is returned
})
```
