An efficient PCA-based color transfer method

An efficient PCA-based color transfer method

Color information of natural images can be considered as a highly correlated vector space. Many different color spaces have been proposed in the literature with different motivations toward modeling and analysis of this stochastic field. Recently, color transfer among different images has been under investigation. Color transferring consists of two major categories: colorizing grayscale images ...

A New Pca–based Robust Color Image Watermarking Method

Although, the possibility of electronic storage and transmission has been bene cial for extending the intellectual communication, the easiness of copying and transmitting the data in the internet has increased the piracy and illegal use of owned artworks. As a result, digital data watermarking, has been under thorough investigation in recent years. The main aim of data hiding is to add some tra...

Wavelet–PCA–Based Compression Method for Color Images

From the birth of multi–spectral imaging techniques, there has been a tendency to consider and process this new type of data as a set of parallel gray–scale images, (instead of an ensemble of an n–D realization). Although, even now, some researchers make the same assumption, it is proved that using vector geometries leads to more realistic results. In this paper, using a proposed PCA–based eige...

An Efficient Perceptual Color Indexing Method for Content-Based Image Retrieval Using Uniform Color Space

Skin Color Detection Using PCA-based Color Representation

Skin color detection is the process that classifies unknown colors into skin or non-skin classes. Skin color detection is preliminary step for facial or gesture analysis and can reduce search space for next higher level processing. In this paper, we show that proposed PCAbased color representation can give better performance than other frequently used color spaces such as XYZ and Luv. For skin ...
