WLS filter based cartoon and texture decomposition for color transfer in fabric images

ABSTRACT:

The analytic study of Color design process in a fabric images is a daunting task. A color design process for fabric images can resort to a solution of a color transfer problem based on given color themes. Usually, the color transfer process contains an image segmentation phase and an image construction phase. In existing work, they designed an enhanced novel color transfer method which efficiently applies the color to the fabric images. This process is carried out in two processes, namely, image segmentation and image reconstruction process. Since, the time taken by image decomposition is of higher, in proposed, we make an attempt to develop novel image decomposition process which intellectually reduces the time taken by decomposed image. We proposed weighted least squares (WLS) filter for image decomposition, it produces efficient result. After that, total generalized variation (TGV) regularizer is used to further improve the performance of image decomposition. Here, the TGV regularizer is good at estimating the weak lightness variation of the cartoon component. Numerical results demonstrate that the proposed color transfer method can generate better results for fabric images.

EXISTING SYSTEM:

In existing, a variational color-theme based method is proposed. The process contains two sequential phases: the image segmentation phase (the first phase) and the new-image construction phase (the second phase).
In the first phase, a target fabric image is partitioned into several regions by colors, where the mean colors of all different regions are combined to be the color theme of the input image. Note that the image segmentation model used is a generalized version of the model, and it can estimate a bias field of the target image from the lightness component of the image. Here, the image refers to its coordinates in the CIELab color space, and the bias field at each pixel indicates the dividing result of the lightness intensity of the pixel by the mean value of the lightness intensities in the region which the pixel belongs to.
In the second phase, for a given color theme, a new image is constructed by changing the estimated color theme of the input image with the given color theme, and the new image is also considered as a color design proposal.
In existing, they proposed one of the novel model for efficient color transfer based on image decomposition and TGV variation.

DISADVANTAGES OF EXISTING SYSTEM:

The constructed images are still not quite satisfactory from vision. In fact, when we compare the constructed image with its corresponding original input image, some geometrical structure details of the constructed image are too smooth, while some artifacts can be found in the constructed image.
In existing, one novel model produced better result but its taking processing time is high in image decomposition stage.

PROPOSED SYSTEM:

In proposed work, we propose a new color transfer model based on novel image decomposition method.

Our proposed method has following steps,

The new color transfer model includes an image segmentation phase and an image construction phase.
In image segmentation phase, we propose a novel image decomposition method. Here, image decomposition means that an input fabric image is decomposed into its cartoon component and its texture component. The advantages of the introduction of image decomposition into image segmentation are that, firstly, the cartoon component better coincides with the local piecewise constant assumption of the image segmentation model than the original input image, and, secondly, the texture component of the image can be used in the image construction phase, which makes the color transfer results containing much more fabric texture details. It is done by weighted least squares(WLS) filter.
After that, the TGV regularization term is used to measure the lightness details of the cartoon component since the TGV regularizer can protect lightness inhomogeneity in each homogeneous color region.
Finally we apply color transfer for reconstructed image from combine of TGV image and texture image. By experiments, we find that our proposed WLS model generates better color transfer results than the existing model.

ADVANTAGES OF PROPOSED SYSTEM:

In this paper the cartoon component instead of the original image is used in the image segmentation phase since the cartoon component coincides with the piecewise-constant assumption better.
Texture component is used for extract the texture details of fabric image.
Processing time is less in image decomposition stage than existing decomposition stage.
