Filter Collection

Image

Get Person Mask

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

Swap the background of a person

let swappedImage:UIImage? = sematicImage.swapBackgroundOfPerson(personUIImage: yourUIImage, backgroundUIImage: yourBackgroundUIImage)

Blur the backgrond of a person

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

Get a prominent object mask

let prominentMaskImage:UIImage? = sematicImage.saliencyMask(uiImage:image)

Swap the background of the prominent object

let backgroundSwapImage:UIImage? = sematicImage.saliencyBlend(objectUIImage: image, backgroundUIImage: bgImage)

Crop a face rectangle

let faceImage:UIImage? = sematicImage.faceRectangle(uiImage: image)

Crop a body rectangle

let bodyImage:UIImage? = sematicImage.humanRectangle(uiImage: image)

Crop face rectangles

let faceImages:[UIImage] = sematicImage.faceRectangles(uiImage: image)

Crop body rectangles

let bodyImages:[UIImage] = sematicImage.humanRectangles(uiImage: image)

Crop an animal(Cat/Dog) rectangle

let animalImage:UIImage? = sematicImage.animalRectangle(uiImage: image)

Crop multiple animal(Cat/Dog) rectangles

let animalImages:[UIImage] = sematicImage.animalRectangles(uiImage: image)

Video

Apply CIFilter to Video

guard let ciFilter = CIFilter(name: "CIEdgeWork", parameters: [kCIInputRadiusKey:3.0]) else { return }
sematicImage.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

sematicImage.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

sematicImage.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

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
})
