Image fusion is performed by combining the data from the multiple spectrums i.e. red, blue, NIR and green, results in enhanced image. Each spectral band has specific features of the palm that collect more information to improve the accuracy and anti-spoofing capability of palm print systems. Principal component analysis (PCA) are used for image fusion line like pattern are most discriminative f...

The printing plate and its characteristics in the conventional printing techniques have a significant impact on print quality and image appearance. In screen printing, a weave of screen mesh i.e. a number of threads per cm, is the most important characteristic of the printing plate, hence the most relevant factor which defines printing quality. Print quality itself is a complex term that includ...

The Clapper-Yule model is the only classical spectral reflection model for halftone prints that takes explicitly into account both the multiple internal reflections between the print-air interface and the paper substrate and the lateral propagation of light within the paper bulk. However, the Clapper-Yule model assumes a planar interface and does not take into account the roughness of the print...

Printing plate performance is one of the crucial factors affecting the printed product quality. In particular, when producing printing plates for larger print runs, a rigorous quality control has to be performed, since any bulk and surface imperfection can have a large detrimental effect on print sharpness, contrast, non-uniformity, colour gamut, and other print properties. In our research two ...

During recent decades due to the increase in pollutants release from various industries, reduction or elimination of volatile organic compounds VOCs has become one of the main purposes of researches in order to protect the environment. In this research, two acrylic emulsion resins and an adhesion promoter polyester emulsion resin were used to optimize water-based printing ink formulation for pr...

agriculture (mechanization), food industry and environment are the concepts that cannot be surveyed separately (because of their interaction). present research aimed to study tomato paste production by applying life cycle assessment. two functional unit of kg co2-eq/ kg tomato and kg co2-eq / kg paste was used. data were collected from one paste factory in alborz province and open-field tomato ...

in this study two modes ofreading (car and traditional print mode) were compared in regards to their effectiveness for l2 reading comprehension. a group of 120 english major students were divided into three classes: car, traditional, and control. based on the english proficiency scores each class was divided into two groups (high and low levels of proficiency). three classes were taught by the ...
