The efficient compression of medical images is important for improved storage and network utilization. The Joint Photographic Experts Group (JPEG) baseline compression algorithm has been widely used in medical image compression. In contrast, JPEG2000 is a relative new compression standard. The purpose of this study is to provide a quantitative comparison of JPEG and JPEG2000 compression effects...

Digital image in raw form require a large amount of storage capacity. Due to limited bandwidth and storage capacity, images must be compressed before storing and transmitting. Image compression means reducing the size of the graphics file, without compromising on its quality. This paper entails the survey of various image compression techniques and highlights the important features of each meth...

BACKGROUND Cardiopulmonary resuscitation (CPR) is a kind of emergency treatment for cardiopulmonary arrest, and chest compression is the most important and necessary part of CPR. The American Heart Association published the new Guidelines for Cardiopulmonary Resuscitation and Emergency Cardiovascular Care in 2010 and demanded for better performance of chest compression practice, especially in c...

this paper describes experimental and numerical investigations on two specimens of frames composed of steel reinforced concrete beam and angle-steel concrete column under horizontal low cyclic loading. based on the test results, the relationship curves of the horizontal load-displacement and the failure modes are acquired. meanwhile the hysteretic behaviors, skeleton curves, stiffness degradati...

background:       lymphedema is a common complication for breast cancer therapy. patients with lymphedema may experience pain and body image issues. this study investigates the effect of combined decongestive therapy and pneumatic compression pump on body image in patients with lymphedema secondary to breast cancer treatment. methods:       42 women with breast cancer related lymphedema partici...

In this paper all basic image compression techniques have been discussed. The image compression techniques which are useful in their related areas are analyzed. Compression methods DCT and DWT recently used for image compression which gives better compression ratio. This review paper gives clear idea about basic compression techniques and method. Keywords— MDP, KLT, SIFT, S-PCA

The pioneer work of image compression/reconstruction based onfuzzy relational equations (ICF) and the related works are introduced. TheICF regards an original image as a fuzzy relation by embedding the brightnesslevel into [0,1]. The compression/reconstruction of ICF correspond to thecomposition/solving inverse problem formulated on fuzzy relational equations.Optimizations of ICF can be consequ...

Polyphase is a common class of pulse compression waveforms in the radar systems. Oppermann code is one of the used codes with polyphone pattern. After compression, this code has little tolerant against Doppler shift in addition to its high side lobe level. This indicates that the use of Oppermann code is an unsuitable scheme to radars applications. This paper shows that the use of amplitude wei...

The normal specifications of motor gasolines as well as their combustion characteristics in internal combustion engines are reviewed in this paper. The effective factors influencing the fuel performance, such as the molecular structure of the fuel constituents, the operating conditions and the atmospheric pressure and temperature are also discussed. A relationship between the optimum octane num...
