In existing methods for segmented images, either edge point extraction or preservation of edges, compromising contrast images is so sensitive to noise. The Degeneration Threshold Image Detection (DTID) framework has been proposed improve the filtered images. Initially, DTID uses a Rapid Bilateral Filtering process filtering edges This filter decomposes input into base layers in framework. With ...

The given key image is converted into gray scale image and after that a matrix is computed with gray scale values of the key image. Then we are collecting the diagonal k...

It is very important to provide security to voting system and mostly which is online one. In this paper we provide security to online voting system with secure user authentication by providing biometric as well as password security to voter accounts. Basic idea behind this is to combine secret key with cover image on the basis of key image. As a result such new image is produced by system calle...

This work proposes a novel scheme of separable reversible data hiding for encrypted image using histogram modification. After the original image is encrypted by the sender, the data-hider embeds the secret message into the encrypted image by a histogram modification and n-nary data hiding scheme. On the receiver side, the secret message can be extracted by the embedding key, and the original im...

the quality evaluation of agricultural products is one of the key factors in promoting their quality. in this study, a method based on combined image processing technique and artificial neural network was presented. separation of touching almonds under different positions is a very important step in design of grading devices. in this study, an image processing algorithm based on extracting crit...

Secured image compression is the key issue in image transmission applications. This paper proposes the idea of combining both compression and security of an image. In the existing methods to encrypt images, the key size is too large since the whole matrix is considered as the key. To solve this problem, encryption through key controlled matrix is constructed using the logistic map in this propo...

A coupled oscillator array is shown to approximate convolutions with Gabor filters for image processing tasks. Pixelated image fragments and filter functions are converted to voltages, differenced, and input into a corresponding array of weakly coupled Voltage Controlled Oscillators (VCOs). This is referred to as Frequency Shift Keying (FSK). Upon synchronization of the array, the common node a...
