This investigation examined how age and test condition affect one's ability to comprehend discourse passages, and determined whether age and test condition affect discourse comprehension and closed-set sentence recognition in a similar way. Young and older adults were tested with closed-set sentences from the newly-created build-a-sentence test (BAS) and a series of discourse passages in two au...

We undertake a study of the performance difference of the discrete cosine transform (DCT) and the wavelet transform for gray scale images. Wide range of gray scale images were considered under seven different types of images. Image types considered in this work are standard test images, sceneries, faces, misc, textures, aerials and sequences. Performance analysis is carried out after implementi...

For the first time in this paper we present results showing the effect of out of plane speaker head pose variation on a lip biometric based speaker verification system. Using appearance DCT based features, we adopt a Mutual Information analysis technique to highlight the class discriminant DCT components most robust to changes in out of plane pose. Experiments are conducted using the initial ph...

—A novel linear transform, called All Phase Biorthogonal Transform (APBT), was generated from All Phase Digital Filter (APDF) theory. APBT can be used in image compression instead of the conventional Discrete Cosine Transform (DCT), and the corresponding image compression scheme is called APBT-based JPEG (APBT-JPEG) which can achieve better coding performance, especially at low bit rates. With...

It was brought to my attention that there are problems related to the recently published article “Evidence of Coal-Fly-Ash Toxic Chemical Geoengineering in the Troposphere: Consequences for Public Health” [1]. Together with the Chief Scientific Officer, Dr. Franck Vazquez, and the Editorial office, we re-evaluated the paper, re-assessed the comments made by the three reviewers and note the foll...

The fingerprint is a physiological trait used to identify a person. In this paper, Performance Evaluation of Fingerprint Identification based on DCT and DWT using Multiple Matching Techniques (FDDMM) is proposed. The fingerprint is segmented into four cells of each size 150*240. The DCT is applied on each cell. The Harr Wavelet is applied on DCT coefficient of each cell. The directional informa...

In this paper a content based image retrieval CBIR is introduced, a color is one of the important features in image processing and CBIR so the Discrete Cosine Transform (DCT) and Color Moment(CM) used to extract features of a query image to compare with image feature in database, the two methods DCT and Color Moment have best result when apply the program by using WANG database images and test ...

due to high speed computer networks, the use of digitally formatted data has increased many folds.the digital data can be duplicated and edited with great ease which has led to a need for effectivecopyright protection tools. digital watermarking is a technology of embedding watermark withintellectual property rights into images, videos, audios and other multimedia data by a certainalgorithm .di...

Abstract Objective: Combining multiple embedded performance validity tests (PVTs) can produce similar classification accuracy to freestanding PVTs. However, there is a lack of research on the incremental predictive power various combinations Thus, we compared eight PVTs assess those that best predict Dot Counting Test (DCT). Method: Sample included 225 patients (mean age=45.96; mean education=1...
