Photoacoustic imaging (PAI) is a rapidly developing emerging non-invasive biomedical
imaging technique that combines the strong contrast from optical absorption imaging and …

With the growth of modern communication technologies, demand for data compression is
increasing rapidly. This Paper gives review of compression principle, classes of …

With increasing demand on digital images, there is a need to compress the image to
entertain the limited bandwidth and storage capacity. Recently, there is a growing interest …

In this paper, we propose a lossless (LS) image compression technique integrating a the
integer wavelet transform with a prediction step that is a simplified version of the median …

Compression of images with tolerable degradation is adopted for efficient data transmission.
Because of the widespread use of computers and the resulting requirement for large-scale …

In this paper, we introduce an improved performance of well-known lossy data compression
techniques, namely Huffman and Arithmetic coding, using a customized scheme that …

Image compression is crucial for shrinking the size of digital photos without reducing quality.
The demand for storage and bandwidth capacity continues to exceed available capacity …

This research emphasizes on problem of determining the suitable threshold value in image
compression without harming the image quality that may affect the Human Visual System …

Cryptography is the study of encoding and decoding the information in secure form, from
unintended recipients. Visual Cryptography is the method of cryptography that encrypts any …

Image compression enables quite exciting solutions in many fields, such as image analysis,
bio-medical image processing, wireless systems and seems to be a key application in …
