The research field of computational aesthetics gives crucial contributions to the development of mechanisms for filtering and/or generating value-laden informational content. This paper acknowledges a recognized escalating problem in the development of contemporary informational technologies and presents a practical solution for communicational quality management by employing an innovative approach to the computational aesthetic evaluation (CAE). After discussing the problem and attempted approaches to its alleviation, the paper offers a novel expert solution by presenting an original research approach and its resulting open-sourced model which outperforms its current state-of-the-art competition in semantic and stylistic classification, at the same time providing an idiomatic measure for objective aesthetic evaluation and demonstrating semantically rich and professionally recognized explanatory power which can serve as the solid basis for development of reliable and user friendly content retrieval, generative or auxiliary design applications. Presented model is resource- and privacy-wise utmost conservative. Its use evades all ethical, legal or security concerns that beset all currently prominent models. Its developmental and operational costs are practically nil.

The paper investigated the experience and emotional reaction of respondents to different newspaper photographic illustrations depending on the media of realization (print in newspaper press, laptop computer screen, and smartphone screen). Due to differences in the formation of basic visual psychophysical reactions in affirmative childhood, the respondents were chosen from two separate age groups: younger from 19 to 23 years and mature from 38 to 49 years. Respondents rated from 1 to 5 the emotional reaction caused by the observed photographic illustration according to the offered reactions: happiness, love, hope, fear, sadness, hatred, anger, envy, shock, sexual attraction, disgust, shame, pride, attraction, and sympathy. Through the research, the difference in experiences and emotional reactions depending on the gender and age difference was monitored. The results of the research indicate that depending on the medium of display, there are significant differences in the experience of photographic newspaper illustrations depending on the age of the respondents, gender, but that previous, but more current, habits of using display technologies also have a significant influence.

A digital camera is generally used for digital recording of photographic images in the RGB system. When such a multicoloured photographic image is converted to black and white using the standard Grayscale conversion in Adobe Photoshop, the colour information, expressed as R, G and B channel values, is lost. This paper analyses the darkening caused by different conversions of the RGB record of a photographic image to a black and white image record. The conversions were performed on three photos, with 10 random colours separated for each photo before conversion. After conversion, the L parameter, which indicates the brightness value, was analysed. The changes in the L parameter due to different methods of photo conversion from multicolour to black and white, such as desaturation, extraction of the R channel, extraction of the G channel and extraction of the B channel, were also analysed.

Understanding abstract concepts of aesthetics and semantics is crucial in developing reliable and verifiable systems for information retrieval or content generation. In this study we explore the space of use-cases where neural networks can aid in deepening the understanding of aesthetic and semantic theoretical principles, their relations, their practical relevance, and possibilities for automation of theory-aligned, and thus explainable, semantic or aesthetic evaluation. We start with pretrained object-recognition vision models, refitted and fine-tuned to discriminate between classes of fine art paintings along two core-semantic axes: abstract-concrete and iconic-symbolic. We then refit the models one more time using the CBM method to make models more reliable and their outputs interpretable in the frame of design- and art-theoretic principles. Finally, we apply a curated collection of xAI methods to analyze, visualize, and contrast the decision-making criteria of four developed models. Our findings show that - for the task of mapping sets of highly distributed, complex and intertwined features - the introduction of narrow concept bottlenecks at the output end of the black-box networks affords for interpretation of models’ outputs, while leaving no negative impact on their classification performance. The methodology developed for this paper presents a transferable framework for amplifying black-box vision-models’ usability and verifiability of their outputs, and it is especially applicable in specialized fields with well-formed theoretical understanding of their respective imaging problem-space. All code developed for constructing, refitting and analyzing models, alongside the datasets created for this study, have been made publicly available under the GPLv3 license.

Multi-scale registration and adaptive feature fusion provide established mechanisms for combining spatial information, but their effectiveness does not establish the benefit of combining drift estimates from independently generated reference patterns. This study proposes a multi-scale latent reference pattern model and its mathematical formulation for geometric drift estimation in printing. Coarse, medium, and fine Poisson-disk patterns provide separate observations for estimating translation, small-angle rotation, and fixed-frequency sinusoidal deformation. Three scale-specific estimators are compared with equal-weight and adaptive multi-scale combinations. The main experiment comprises 250 independent synthetic realizations, each evaluated under 16 combinations of Gaussian noise and blur. All three scales produced valid estimates in all 4000 scenario realizations. The fine scale had the lowest individual estimation errors, while equal weighting achieved the lowest mean errors among the five estimators in the main experiment. Mean deformation RMSE was 0.056848 px for equal weighting and 0.058735 px for adaptive weighting. Additional synthetic experiments examine threshold sensitivity, rigid and thin-plate-spline baselines, pooled estimation, and the relationship between adaptive weights and estimation error. Rigid registration was most precise in the rigid-only control, while pooled estimation achieved the lowest mean exact-field error under sinusoidal deformation. The contribution is a mathematically specified reference-pattern model and a controlled evaluation that identifies scale-dependent precision and limitations of the tested reliability indicator. The results support computational feasibility under the specified synthetic conditions. They do not establish an accuracy advantage for adaptive weighting or measurement performance on physically printed and captured patterns.
