In the article a method of compression of High Dynamic Range of Infrared images and its details enhancement was proposed. The method is based on aggregation of partial images with different ranges of pixel values generated on the basis of weighting function. Aggregation of images could be performed according to proposed scheme with use of the optimal algorithm selected by user. Preliminary resu...

many efforts have been made to model the the hot deformation (dynamic recrystallization) flow curves of different materials. phenomenological constitutive models, physical-based constitutive models and artificial neural network (ann) models are the main methods used for this purpose. however, there is no report on the modeling of warm deformation (dynamic spheroidization) flow curves of any kin...

Dynamic range compression is a nonlinear, time dependent audio effect. As such, preferred parameter settings are difficult to achieve even when there is advance knowledge of the input signal and the desired perceptual characteristics of the output. We introduce an automated approach to dynamic range compression where the parameters are configured automatically based on real-time, side-chain fea...

The paper proposes a novel approach to the classification of compressed videos containing dynamic textures. The term dynamic texture is usually used with reference to image sequences of various natural processes that exhibit stochastic dynamics (e.g., water, fire and windblown vegetation). Description and recognition of dynamic textures have attracted growing attention. Although one of the most...

Dynamic range compression serves different purposes in the music and hearing-aid industries. In the music industry, it is used to make music louder and more attractive to normal-hearing listeners. In the hearing-aid industry, it is used to map the variable dynamic range of acoustic signals to the reduced dynamic range of hearing-impaired listeners. Hence, hearing-aided listeners will typically ...

Dynamic recrystallization, DRX, behaviour of a precipitation hardened, PH, stainless steel was studied in connection with microstructural developments in a compression test. The experimental results showed that the dominant mechanism of softening is DRX, but at high strain rates and low temperatures, ie, high Zener-Holman parameter, Z, work hardening and dynamic recovery, DRV, produced a pancke...

This paper presents the EPFL proposal to MPEG-4 video coding standardization activity [1]. The proposed technique is based on a novel approach to audio-visual data compression entitled dynamic coding. The newly born multimedia environment supports a plethora of applications which can not be covered adequately by a single compression technique. Dynamic coding o ers the opportunity to combine sev...

Introduction Dynamic loading is essential for maintaining intervertebral disc health since a major nutritional mechanism is load-induced fluid transport, and intermittent stress can stimulate matrix production. Yet, excessive dynamic loading can be detrimental. Currently, the boundary between therapeutic and injurious spinal stress is undefined. To address this, we have developed an approach th...

The growth of computational power of contemporary hardware causes technologies working with 3D-data to expand. Examples of the use of this kind of data can be found in geography or gaming industry. 3D-data may not be only static, but also dynamic. One way of animated 3D-data representation is expressing them by ”dynamic triangle mesh”. This kind of data representation is usually voluminous and ...

Since the standardization of the JPEG 2000, it has found its way into many different applications such as DICOM (digital imaging and communication in medicine), satellite photography, military surveillance, digital cinema initiative, professional video cameras, and so on. The unified framework of the JPEG 2000 architecture makes practical high quality real-time compression possible even in vide...
