Least Square Backpropagation(LSB) algorithm is employed to train a three-layer neural network for segmentation of Magnetic Resonance(MR) brain images. The simulation results demonstrate the use of LSB neural Network as a promising method for the segmentation of multi-modal medical images. The training time has been dramatically reduced comparing with that of BP network. The influence of the num...

This paper proposes a 240 frames/s 2.1 M-pixel CMOS image sensor with column-shared cyclic ADC that consumes low power of 90 μW/column at 1.5 V supply and is applicable to the fine pixel pitch of 2.25 μm. The prototype sensor was fabricated in a 0.13-μm 1P4M CMOS technology. The measured DNL and INL are +0.59/-0.83 LSB and +2.8/-3.6 LSB, respectively. The measured maximum pixel rate is 500 Mpix...

The aim of the steganography methods is to communicate securely in a completely undetectable manner. LSB Matching and LSB Matching Revisited steganography methods are two general and esiest methods to achieve this aim. Being secured against first order steganalysis methods is the most important feature of these methods. On the other hand, these methods don't consider inter pixel dependency. The...

As we all know security is needed when we want to send data over any medium so this requires a secure medium to send data. That’s why steganography comes in mind whose aim is to send data securely without knowing of any hacker. In this paper, a new technique is projected whose aim is to keep secrete communication intact. The proposed method blends the advantage of 2 bit LSB and XOR operation. I...

We serendipitously find a new nearby Low Surface Brightness (LSB) galaxy from SDSS database. We estimate oxygen abundance of its H ii region SDSS J121811.0+465501.2 from electron temperature, as well as for another H ii region, SDSS J135440.5+535309.6, located in irregular LSB galaxy UGC8837. These two extragalactic H ii regions were classified as stars in the SDSS-DR4 database, and were found ...

Today’s large demand of internet applications requires data to be transmitted in a better manner. Data is transferred in public communication system is not secure because of interception and improper manipulation by eavesdropper. So the better solution for this issue is Steganography, which is the technique of writing hidden messages in such a way that no one, apart from the sender and main rec...

The Digital watermarking is a field of information hiding that entails the crucial in original data order to prevent illegal duplication and distribution multimedia such as image, video, text ect.. In this paper, we present two techniques embed watermarks cover image. first Least Significant Bit (LSB) method, which spatial domain technique considered fragile against attacks other operations. se...

Digital Rights Management (DRM) system is the effective scheme for digital transactions. The main disadvantage of DRM is that once the content is decrypted, it can be easily copied using widely available utilities. It can be removed by using protection system like steganography. Steganography is the art of communicating in a way which hides a secret message into the main information or cover. T...

There is an increasing focus on promoting person-centred systems across continuing care settings, emphasizing the need to enhance the quality of life of older adults. Life story books (LSB) can provide a holistic view of older adults, promote relationship-centred care and enhance person-centred care. The process of developing LSB involve collecting and recording aspects of a person's life both ...

We detect 21-cm emission from the Low Surface Brightness (LSB) galaxy SBS 1543+593, which gives rise to a Damped-Lyα (DLyα) absorption line in the spectrum of the background QSO HS 1543+5921 (ze = 0.807). We obtain an accurate measure of the velocity of the H I gas in the LSB galaxy, v = 2868 km s, and derive a mass of MH I = 1.3× 10 9 M⊙. We compare MH I with limits obtained towards two other ...
