Printing. Publishing. Book trade Abstract Vizualna komunikacija u suvremenom digitalnom okruženju pretežno se temelji na
multimedijskim web tehnologijama. Metodologija izrade web sjedišta koje se može dinamično
prilagoditi karakteristikama prikaznih uređaja (engl. display devices) naziva se prilagodljivi
(engl. responsive) web dizajn. Ugradnja prilagodljivih slika podrazumijeva izradu više
optimiziranih varijanti originalne slike. U ovom doktorskom radu razmatraju se odabrani
postupci automatizirane obrade digitalnih fotografija u prilagodljivom web dizajnu, realizirani
pomoću ImageMagick command-line alata magick convert i programskog jezika PHP u CLI
(engl. Command Line Interface) modu rada. Performanse procesa mjere program GNU time i
razvijeni monitor radne memorije, a SSIM metodom utvrđuje se kvaliteta izlaznih fotografija,
pomoću ImageMagick command-line alata magick compare. Razvijena eksperimentalna metoda
temelji se na računalu Raspberry Pi 3 Model B+ i operativnom sustavu Raspbian Buster Lite. Cilj
istraživanja je odrediti smjernice za optimizaciju performansi procesa obrade fotografija u
prilagodljivom web dizajnu, na temelju izbora najboljeg kompromisnog rješenja postupka iz
definiranog seta alternativa. Provedbom eksperimentalne metode snimljeni su relevantni podaci o
svakom razmatranom postupku. Primjenom izrađenog laboratorijskog prototipa obrađeni su
snimljeni podaci i provedeno je višeatributno odlučivanje (engl. Multiple Attribute Decision
Making – MADM), metodom jednostavnog zbrajanja težina (engl. Simple Additive Weighting –
SAW). Time je utvrđena konačna ocjena svakog postupka, prema definiranim kriterijima.
Razmatranjem rezultata istraživanja utvrđene su smjernice za optimizaciju performansi procesa
obrade fotografija u prilagodljivom web dizajnu. Time je uspješno ostvaren cilj istraživanja i svi
predviđeni znanstveni doprinosi. Također, potvrđene su sve hipoteze istraživanja. Zaključeno je
da se izrađeni laboratorijski prototip, razvijena eksperimentalna metoda i pripadajuća programska
podrška mogu uspješno koristiti za evaluaciju postupaka obrade digitalnih fotografija u
prilagodljivom web dizajnu.
Abstract (english) Visual communication in modern digital environment is mostly based on multimedia web
technologies. Development methodology for websites that can dynamically adjust to the display
device characteristics is called responsive web design. Implementation of responsive images
requires creation of multiple optimized versions of original image. This dissertation is
considering selected automated digital photo processing procedures in responsive web design,
that are performed using magick convert ImageMagick command-line tool and PHP
programming language. Selected performance parameters are measured using GNU time program
and developed RAM memory monitor, while SSIM method is used to determine output image
quality, by utilizing the magick compare ImageMagick command-line tool. Developed
experimental method is based on the Raspberry Pi 3 Model B+ computer and Raspbian Buster
Lite OS. The research aims to determine guidelines for performance optimization of digital photo
processing in responsive web design, based on the best compromise procedure solution selection,
from defined set of alternatives. By performing the experimental method, relevant data on each
considered procedure were recorded. By utilizing the developed laboratory prototype, recorded
data were processed and Multiple Attribute Decision Making (MADM) was performed, using the
method of Simple Additive Weighting (SAW). That gave the performance score of each
considered procedure, according to the defined criteria. Based on the research results, guidelines
for digital photo processing optimization in responsive web design have been established. The
research goal and all planned scientific contributions were successfully achieved. Also, all
research hypotheses were confirmed. It was concluded that the developed laboratory prototype,
experimental method and related software can be successfully used for the evaluation of digital
photo processing procedures in responsive web design.
