The proposed color BTC algorithm can adaptively truncate a pixel block into one or two output classes according to the distribution of color values inside the blocks. The experimental results show that the compression ratio will increase as compared with existing color BTC algorithms and the picture...
Summary: Color and binary images are popular subjects for data hiding. In this paper we propose a method to controlling quality of hiding secret data in binary images by using small blocks of 12 pixels with a restriction that in each block at most two pixels are changed to embed 6 secret ...

This chapter describes work undertaken at BT Laboratories to produce a system, based on the use of neural network feature detectors, to robustly locate and track features in digital image sequences. We have concentrated on the location of eyes and mouths in human head-and-shoulders images, altho...
After TMA core extraction and color enhancement, five different flows of independent and ensemble deep learning were applied. Training and testing data with 2144 and 13,006 cores included three classes: tumor, normal or “other” tissue. Ground-truth data were collected from 30 ngTMA slides (n...

Among the former category, we adopted JPEG2000 as the best one, and for the latter category, we assumed the context based coding, which refers to the numbers of black pixels in several neighboring blocks. By setting same bit rate per pixel for these two methods, the picture quality of the...
When youadd a modern page to a site, youcan add and customize web parts, which are the building blocks of your page. Note:Some functionality is introduced gradually to organizations that have opted in to theTargeted Release program. This means that you may...
the binary watermarking image which has been scrambled by implementing Arnold transform is embedded into the host image.In procedures of extracting,embedded sequences in each image blocks are extracted.Correlations between extracted sequence and two pseudo random sequences are calculated respectively....
Additional computational burden is caused mainly by the need of choosing the pixels from a patch which are most similar to the one in block center. However, in practical applications significantly larger blocks and patch sizes are needed by the NLM, which translates into higher computational ...
