The True Colors of “False” Color: Representing Data Chromatically in NASA Films

This paper investigates the multifaceted uses of color — not (only) to aesthetic ends, but as a tool for translating data into narrative — in a corpus of recent NASA films. Often called ‘false’ color or accused of manipulation, these uses of digital color stray from photorealism but nonetheless have a direct, measurable relationship with physical reality: they use data to render visible that which lies outside the spectrum of visible light. The focus of this paper is on the truth status of these digital films and on the practices used to produce them. It situates them, as a corpus, within and in response to film studies historiographies of color centered around spectacle and the dichotomy of fantasy versus reality, addressing how color can deploy the powers of the false to reveal otherwise invisible truths through art and artifice.

Неразрушающий контроль стальных тосов с использованием оптимизированного метода опорных векторов

In this paper, to address the problems of poor signal noise reduction and low recognition rate in wire rope leakage magnetic detection, we propose the algorithm MSVDW, which uses a combination of median filtering, singular value decomposition (SVD) and wavelet transform, to denoise the collected three-dimensional MFL signals. Then, false color is used to enhance the image. The image is then localized and segmented using the modulus maximum method. The color moments are extracted from the images and used as the input of the particle swarm algorithm optimized support vector machine (PSO-SVM) for training and recognition. The experimental results show that the noise reduction algorithm proposed in this paper effectively reduces the noise of the leakage signal, the false color image enhances the defect image information, and the algorithm of PSO-SVM greatly improves the recognition rate of defects.

Interpretation of the Geological Romance of Kendari Bay Using Landsat 5 TM

Kendari Bay is part of Kendari City. Kendari Bay is a city landmark in addition to its economic and environmental functions.. The condition of Kendari Bay is experiencing a fairly high sedimentation problem, so that it begins to cause problems with land availability and space utilization patterns in the Kendari Bay area. The endogenous process of dynamic earth activities is a part that needs to be considered in managing that problems. This study aims the geological conditions of Kendari Bay by using remote sensing as a form of studying the geological conditions of Kendari Bay. Using Landsat 5 TM imagery in 1990, it was used to see the natural geological conditions of Kendari Bay, using the false color composite method and interpretation of photo images visually and validated through field observations. Landsat image processing and interpretation using Quantum GIS, resulted in Kendari bay can be divided into several physiography, namely coastal zone, estuary zone, fluvial zone, plain zone, hill zone, and mountain zone (Head land). The physiography can be seen from the geological characteristics such as the lithology which is composed of alluvial deposits to limestone. The results of interpretation of composite color images and validation of direct observation data in the field show a qualitative suitability.

How Microaggressions Reinforce and Perpetuate Systemic Racism in the United States

The consequences of racial microaggressions are most often discussed at an interpersonal level. In this article, we contend that microaggressions play an important role in maintaining systems of racial oppression beyond the interpersonal context. Specifically, we illustrate how microaggressions establish White superiority in the United States by othering people of color (e.g., treating people of color as if they are not true citizens) and communicating that they are inferior (e.g., environmental exclusions and attacks, treating people of color as second-class citizens). We also present evidence that microaggressions play a role in protecting and reinforcing systemic racism. By obscuring systemic racism (e.g., false color blindness, denial of individual racism) and promoting ideas that maintain existing systemic inequalities (e.g., the myth of meritocracy, reverse-racism hostility), microaggressions provide cover and support for established systems of oppression. Overall, we find considerable evidence—from both empirical studies and real-world examples—that microaggressions contribute to the maintenance of systems of racial oppression in the United States. We conclude with a discussion of how we might begin to challenge this cycle by increasing awareness of systemic racism and the microaggressions that aid in its perpetuation.

Identification of Continental Wetlands Using Different Orbital Remote Sensors

This paper evaluates the potential of false-color composite images, from 3 different remote sensing satellites, for the identification of continental wetlands. Landsat 8, Sentinel-2 and CBERS-4 scenes from three different Ramsar sites (i.e., sites designated to be of international importance) two sites located within the Mato-Grossense Pantanal and one within the Sul-mato-grossense were used for analyses. For each site, images from both the dry and rainy seasons were analyzed using Near-Infrared (NIR), Shortwave Infrared (SWIR), and visible (VIS) bands. The results show that false-color composite images from both the Landsat 8 and the Sentinel-2 satellites, with both SWIR 2-NIR-BLUE and NIR-SWIR-RED spectral band combinations, allow the identification of wetlands.
