CN1745386A - Image blending by guided interpolation - Google Patents

Abstract

A blended result image is computed using guided interpolation to alter image data within a destination domain. The destination domain may be altered based on a guided interpolator that is either dependent or not dependent upon a source image. When blending a source region into a destination region of an image, guided interpolation eliminates or minimizes apparent seams between the inserted region and the rest of the image. A variety of interpolation guides may be used to yield different effects in the blended results image. Such interpolation guides may include without limitation an identity guide, a smooth guide, a filtering guide, a transparent guide, a masking guide, and a weighted average combination of various guides.

For example, in Fig. 1, the user wishes and will be inserted in the target image 104 from the sun 100 of source images 102.Simply duplicating in the paste operation, the user will be in source images 102 selects or cutting, duplicates the zone of institute's cutting and the zone of institute's cutting is attached to desired locations in the target image 104 along the circumference of the sun 100.Perhaps, can use simple drag-and-drop operation with similar fashion.Yet, in these two kinds of methods, the border between the institute clipping region of insertion and the remainder of target image 104 (or claim " seam ") can seem any irregular in very discontinuous and the reflection trimming operation.In addition, when being inserted into when representing the target image 104 of sky by dusky background, any part of the background of the sun in the source images 102 of being caught in trimming operation (that is, pure light blue in the coloured image) will show as stiff discontinuous.In other words, the cutting of being inserted partly would not blend in the target image 104.

The replacement method of a kind of being called " clone " relates to the anchor point that defines in source images.On target image, use paintbrush to control the zone that source image data should be copied in the objective definition image wherein.The result is similar to duplicate and pastes or drag and drop replacement method.

In addition, other image-editing operations also can relate to the outward appearance that changes selected areas in the image.For example, can the graduation image regional texture, can make background or prospect decolouring or can on certain zone of image, carry out illumination change.Yet this type of editing operation also can be introduced the problem of seam between editing area and original image remainder.

In order to improve the result of these existing methods, can carry out part " emergence " operation and come the cutting part of cache insertion and the seam between destination image background.Such emergence method is usually directed to view data is blured or smear at seam crossing, cutting part of being inserted to approach and the graduation transition between destination image background.Yet the operation of sprouting wings may produce unsafty result, because seam is only replaced by fuzzy view data.In addition, existing method can not provide various mixed mode to allow the user image section that is inserted to be integrated in the target image best.

Therefore, in many general case, existing cutting and cloning process provide flexible and seamless image to insert and editor unsatisfactorily.

Interpolation instructs title	Symbol	Interpolation instructs definition
			Identical	I	?v＝f *
Smoothly	S	?v＝0
			Filter	F	?v＝F(g)

Transparent	T	v＝1 [|f*|＞|g|]f *+1 [|g|＞|f*|]g
			Mask	M	v＝1 [|f|＞τ]f
The weighted mean combination	W	V=α I+ (1-α) F (for example)

For example, identical interpolation instructs I to cause no change (therefore, f=f in the target image ^*).Alternatively, smoothly interpolation instructs S to change target image.The Euler-Lagrange equation that instructs S to be associated with level and smooth interpolation is:

f=0 on the Ω, its f| _Ω=f ^*| _Ω,

And be considered to have the Laplace's equation of Dirichlet boundary conditions.Unique solution with Laplace's equation of Dirichlet boundary conditions often is known as " film interpolation type (membrane interpolant) ".The discrete form of head it off causes image-region very level and smooth or fuzzy among the Ω of territory in each color channel.Level and smooth interpolation instructs S the gradient of this inside, territory to be minimized (" the empty guidance "), and causes being positioned at the very level and smooth interpolation of the borderline color in territory.Level and smooth interpolation instructs S to be used by the computer graphical region-filling algorithm, comprises the filling algorithm of polygon or arbitrary shape.
