A method for quantification of images of immunohistochemically stained cell nuclei by computing area proportions is presented. The image is transformed by a principal component transform. The resulting first component image is used to segment the objects from the background using dynamic thresholding of the P2/A-histogram, where P2/A is a global roundness measure. Then the image is transformed ...

Fast and accurate 3D object reconstruction and partial 3D component retrieval from 2D image slices represent a difficult and challenging problem. To group related objects on different layers in an image stack, image segmentation and sequential matching of adjacent 2D objects have to be preformed. Object matching involves heavy computing and is time consuming. In this paper, we propose a new app...

This paper proposes an algorithm which automatically aligns and stitches the component medical images (fluoroscopic) with varying degrees of overlap into a single composite image. The alignment method is based on similarity measure between the component images. As applied here the technique is intensity based rather than feature based. It works well in domains where feature based methods have d...

Document image matching is the key technique for document image registration and retrieval. In this paper, a new matching method based on document component block list (CBL) is proposed. A document image is ®rstly parsed into a number of component blocks that are de®ned as non-adherent rectangular areas of substantial document contents. Then these blocks are organized as a list, on which severa...

Shading and reflectance images, which are commonly called intrinsic images, are useful in many computer vision applications. A number of methods have been proposed to extract those images. Unfortunately, all of these methods assume diffuse only reflections and deem highlights to be outliers. To overcome the presence of highlights, usually reflection components separation is applied before attem...

a novel fast image fusion scheme based on principal component analysis (pca) and lifting wavelet transformation (LWT) is proposed. Firstly, the principal component images of the registered original colour image are obtained by pca transformation. Then, the first principal component image and near infrared imagery are merged using lifting wavelet transformation (LWT) based on regional features. ...

Blocking artifact, characterized by visually noticeable changes in pixel values along block boundaries, is a common problem in block-based image/video compression, especially at low bitrate coding. Various post-processing techniques have been proposed to reduce blocking artifacts, but they usually introduce excessive blurring or ringing effects. This paper proposes a self-learning-based post-pr...

background: sexual satisfaction is a vital component in marital satisfaction and life quality. the appraisal has influence sexual satisfaction. the previous study shows that people use methamphetamine and opium for enhancing sexual functioning. objectives: the current study was designed to examine the impact of methamphetamine and opium use in sexual satisfaction and body image. patients and me...

In this paper, a progressive image compression and transmission using edge detection scheme is adopted. The image is decomposed into two (primary and secondary) components. Canny method is adopted to detect the edges of the encoded image. These edges are replaced with a pre-designed nine basis nameplates. Then, the Macro edge detection technique is used to reduce the number of these nameplates ...
