Motion/Moving effect with animation on still image

I am trying to implement animation in a still image in a user-guided direction, something like this:

Original image

Expected result

For this, I have tried the CIBumpDistortionLinear CIFilter. It is animating, but the animation is not exactly like that.

let bumpDistortionLinearParams: [String: AnyObject] = [
    kCIInputImageKey: coreImage!,
    "inputCenter" : CIVector(string: coordStr),
    "inputRadius": 300.0 as AnyObject,
    "inputAngle" : 90.0 as AnyObject,
    "inputScale" : 0.1 as AnyObject
]

let bumpDistortionLinear = CIFilter(name: "CIBumpDistortionLinear", parameters: bumpDistortionLinearParams)
