Weak Supervision in Enemy Detection Based on Computer Game Output Video Stream
No full textThis work contains a solution for image classification and enemy
detection in the output video stream of a computer game. Weak supervision
was used to achieve the goal. It shows that an image dataset with a
certain number of incorrect classification labels can be used to correctly
build a classification model that distinguishes between images containing
and not containing an enemy. Based on the results of such classification
stage and the use of class activation maps, a method for detecting enemies
on positively classified images was proposed. The tedious process of image
labeling, which is necessary for supervised learning, does not occur here

Hashtag Similarity Based on Laplacian Eigenvalue Spectrum
No full textHashtags play nowadays an important role in the current social
media world. They are usually deemed to represent topics of e.g. tweets.
As the number of hashtags is growing, an overview of the information flow
requires some method of grouping these hashtags. The grouping requires a
similarity measure. In this paper we propose a novel measure of similarity
between hashtags based on the Graph Spectral Analysis
Proximity and temporality: The role of weekly markets in the metropolitan food system of Barcelona
No full textThis paper analyses the role of weekly markets in the food supply system in metropolitan Barcelona, understanding their form, measures and urban role in relation to market halls and other grocery stores. Quantitative – in relation to the population they serve, the area they occupy, the distances they are from other providers – and qualitative – about what types of food and what variety they offer – approaches are based on drawings made by the authors that try to capture the architectural form and urban insertion of these food suppliers. At a time when proximity has set the agenda of urban interventions; and in which tactical and strategic urban planning are part of ongoing metropolitan transformations, looking at this ephemeral formalization of essential commerce acquires a structural meaning related to urban form. The topic addressed is part of an investigation started in 2018 that relates the urban form of Barcelona with the food supply system. The specific look at the existing weekly markets aims to prove the effectiveness of these pieces as tools to strengthen the metropolitan food system
Autoregressive Label-Conditioned Autoencoder for Controllable Image-To-Video Generation
No full textGenerating videos from a single image with user-controlled attributes
is a complex challenge in the field of computer vision, despite the significant
advancements recently made in the field. This paper presents a novel
approach to tackle this issue, leveraging a convolutional autoencoder with
supervised principal component analysis and autoregressive inference step.
The efficacy of the proposed method is evaluated on two datasets – MNIST
handwritten-digits and time-lapse photos of the sky. Results from both quantitative
and qualitative analyses show that the proposed approach produces
high-quality videos of variable duration with user-defined attributes, while
preserving the integrity of original image contents
Reality vs Regulation: Informal Practices of Spatial Development in Krasnodar, Russia
No full textIn the research environment, informal urban development has traditionally been studied in the cities of the Global South. However, in the Eastern European context informal urban development differs as land use regulation goes through the process of post-socialist transformation. Krasnodar is one of the biggest and fastest growing cities in Russia where informal construction practices and bottom-up approaches in spatial redevelopment are widely spread despite the strict regulation of housing construction and precise tools for identification of informality. Present work is a step towards the discovery of this phenomenon. In the spotlight we put the exploration of inner synergetic inconsistency of legal relations, connecting economic, institutional, demographic, and sociopolitical context to understand the contradiction between formal and informal urban life. The research methods include spatial and regulatory documents analyses, in-depth interviews with different collective actors (city administration, activists, experts in urban development, locals living in informal). The core of the research relates to the machinery of the conflict behind the legalization process. Findings of this work illustrate a number of reasons behind the spread of informal settlements in Krasnodar and their role in urban development. While administrative power does not seek compromise with locals and migrants, the mistrust of others embodies itself as unguided and spontaneous urban development

Typo-morphology in the Urban Renewal Application – Case Study of Urban Design Project in Changting Town, China
No full textTypo-morphology can be seen as the research perspective and methodology of urban morphology. The terms typo-morphology are typological and morphological because they describe urban forms according to the detailed classification of building types. Typo-morphology links together a series of academic terms in urban morphological research such as type, typological process, and morphological region, emphasizing the relationship between building types and overall form in the evolution of urban morphology. To relate urban morphological research to practice, it is worthwhile to know whether these terms are still relevant in urban practice, and what their significance is. This study examines these urban morphological terms in the practical utility and value through the case of our urban renewal projects of Changting Town, a historic town in the south of China. First of all, investigation and learning of local building types are the tool to understand the way of changing by analyzing local typological processes. Secondly, clarifying morphological regions of the town based on type helps us to produce the design guides of the incremental process for renewal experienced in existing urban areas. Finally, we have found the characteristics of the tangible form of a street block based on the historical housing types, and the quantified urban form characteristics are translated into urban design control indicators. The paper concludes that the term Typo-morphology and its associated terms are meaningful in urban morphological practice which are the bridges to help the application of urban morphology turn to design control
The Latin American city recodified? Pandemic and emerging urban legislation
No full textCity, like living organisms, originates from codes, structured information in the form of rules that condition the physical form and performance of urban space. Usually, the so-called urban codes clash with the spontaneous nature
of the city, with the urban Kháos that contextualizes the free creation (poiesis) of human collectives. This is a comparative study focusing on the urban codes created to address the pandemic. The objective is to build an overview of these innovations in the region. The sample is made up of official norms published in pandemic, directly linked to urban planning, and building
control (urban form). The countries analyzed are Brazil, Mexico, Argentina, Peru, Colombia and Chile. The study uncovers a shared interest in facing future urban problems, in contrast to the inconsistency of proposed legal
instruments. Factors such as the lack of articulation, validity time, ambiguity, among others, accentuate this problem. Likewise, it evidences that political situation of each country has a significant influence on the development of these norms and the possibility of their long-term impact. In summary, the global emergency has produced opportunities to transform urban systems
from their internal rules; however, there are very few successful examples in this field. Therefore, Latin American cities have the task of learning from this defeat to lay the foundations for a more resilient and sustainable urban future
