the extent to which written corrective feedback on linguistic errors can play a role in helping l2 writers improve the accuracy of their writing continues to be an issue of interest to researchers and teachers since truscott (1996) mounted a case for its abolition. while there is growing empirical evidence that written corrective feedback can successfully target some types of linguistic error (...
This paper describes three methods to encode a region of interest (ROI) arbitrary shape in the JPEG standard. The ROI is part image encoded with higher quality than rest image. Two described are based on thresholding DCT coefficients. last method early termination entropy coding phase. All fully compatible existing decoders. Using ROI, it possible reduce bitrate only fraction original value. re...
with the increasing population and the need for more food, as well as with the development of science and technology, human approach to unnatural and often chemical inputs to increase agricultural production has been a great expansion and problems such as increased cancers, chronic diseases has created environmental pollution. implementation of organic organic is a solution to these problems . ...
A new transform is presented that utilizes local radial symmetry to highlight points of interest within a scene. Its lowcomputational complexity and fast runtimes makes this method well-suited for real-time vision applications. The performance of the transform is demonstrated on a wide variety of images and compared with leading techniques from the literature. Both as a facial feature detector ...
Regression analysis is probably one of the most used statistical techniques. We consider the case when the regression function is monotonically changing with some or all of the predictors in a region of interest. Restricted confidence interval for the mean of the regression function is constructedwhen two predictors are present. Earlier analyses would allow an investigator either to ignore mono...
We present a method to correct motion in fetal in-utero scan sequences. The proposed approach avoids previously necessary manual segmentation of a region of interest. We solve the problem of non-rigid motion by splitting motion corrupted slices into overlapping patches of finite size. In these patches the assumption of rigid motion approximately holds and they can thus be used to perform a slic...
Results from an experiment on perception of lexical pitch accents in Gothenburg Swedish (11) showed that both higher initial F0 plateaux and later falls biased native listeners toward the Accent 2 category, while lower plateaux and earlier falls biased toward Accent 1. Segerup and Nolan interpret this as evidence for a perceptual mechanism integrating scaling and timing information, which they ...
