Pengaruh Warna Kemasan Terhadap Persepsi Rasa Pada Produk \ud Minuman
Strategy color packaging is a technique that affects the consumer perception of a product. With the influence of perception, the marketers will be able to win marketing competition, because basically competition in marketing, in addition to fighting product, is also a battle of perception. \ud
This study aims to test the hypothesis of the influence of packaging color (blue, white, red) on the perception of taste in beverage products. The design of this study using laboratory experimental approach Within the subject. The participants in this study were college students as \ud
many as 30 people. In conducting the study, 30 students are divided into 6 groups, where each group consisted of 5 participants. Sampling technique used in this study is simple random sampling. Hypothesis test used in this study is the statistical test Manova (multivariate analysis \ud
of variance). \ud
Hypothesis test results showed that: (1) there is a color effect on the perception of taste in the bottled beverage products (F=6.785, sig=0.000). (2) there is a color effect on the perception of color packaging sweetness (F=24.30, sig =0.000<0.01), there is the influence of packaging color \ud
of sour taste (F=7964, sig =0.001<0.01), there is a color effect on freshness taste perception (F=20,101; sig=0.000<0.01). The analysis result also shows that there is no influence of color on the saltiness taste perception (F=0431; sig=0.430> 0.05), and no influence of color packaging to bitter taste perception (F=0507;sig=0.604>0.05). \ud
Based on the results of this study is recommended to producers for use colors that match packs flavor desired by the consumer
Modelling, Measuring and Compensating Color Weak Vision
We use methods from Riemann geometry to investigate transformations between
the color spaces of color-normal and color weak observers. The two main
applications are the simulation of the perception of a color weak observer for
a color normal observer and the compensation of color images in a way that a
color weak observer has approximately the same perception as a color normal
observer. The metrics in the color spaces of interest are characterized with
the help of ellipsoids defined by the just-noticable-differences between color
which are measured with the help of color-matching experiments. The constructed
mappings are isometries of Riemann spaces that preserve the perceived
color-differences for both observers. Among the two approaches to build such an
isometry, we introduce normal coordinates in Riemann spaces as a tool to
construct a global color-weak compensation map. Compared to previously used
methods this method is free from approximation errors due to local
linearizations and it avoids the problem of shifting locations of the origin of
the local coordinate system. We analyse the variations of the Riemann metrics
for different observers obtained from new color matching experiments and
describe three variations of the basic method. The performance of the methods
is evaluated with the help of semantic differential (SD) tests.Comment: Full resolution color pictures are available from the author
On color image quality assessment using natural image statistics
Color distortion can introduce a significant damage in visual quality
perception, however, most of existing reduced-reference quality measures are
designed for grayscale images. In this paper, we consider a basic extension of
well-known image-statistics based quality assessment measures to color images.
In order to evaluate the impact of color information on the measures
efficiency, two color spaces are investigated: RGB and CIELAB. Results of an
extensive evaluation using TID 2013 benchmark demonstrates that significant
improvement can be achieved for a great number of distortion type when the
CIELAB color representation is used
Protection of Child Witnesses and the Right of Confrontation: A Balancing of Interests
We introduce normal coordinates in Riemannspaces as a tool to construct color-weak compensation methods.We use them to compute color stimuli for a color weakobservers that result in the same color perception as theoriginal image presented to a color normal observer in the sensethat perceived color-differences are identical for both. Thecompensation is obtained through a color-difference-preservingmap, i.e. an isometry between the 3D color spaces of a colornormaland any given color-weak observer. This approach usesdiscrimination threshold data and is free from approximationerrors due to local linearization. The performance is evaluatedwith the help of semantic differential (SD) tests.Virtual Photo Set (VPS)European Community’s Seventh Framework Programme FP7/2007-2013 - Challenge 2 Cognitive Systems, Interaction, Robotics - under grant agreement No 247947 - GARNICS
Digital Color Imaging
This paper surveys current technology and research in the area of digital
color imaging. In order to establish the background and lay down terminology,
fundamental concepts of color perception and measurement are first presented
us-ing vector-space notation and terminology. Present-day color recording and
reproduction systems are reviewed along with the common mathematical models
used for representing these devices. Algorithms for processing color images for
display and communication are surveyed, and a forecast of research trends is
attempted. An extensive bibliography is provided
Color Relationism and Enactive Ontology
In this paper, I present the enactive theory of color that implies a form of color relationism. I argue that this view constitutes a better alternative to color subjectivism and color objectivism. I liken the enactive view to Husserl’s phenomenology of perception, arguing that both deconstruct the clear duality of subject and object, which is at the basis of the other theories of color, in order to claim the co-constitution of subject and object in the process of experience. I also extend the enactive and phenomenological account of color to the more general topic of the epistemological and ontological status of sensory qualities (qualia), outlining the fields of enactive phenomenology and enactive ontology
A statistical reduced-reference method for color image quality assessment
Although color is a fundamental feature of human visual perception, it has
been largely unexplored in the reduced-reference (RR) image quality assessment
(IQA) schemes. In this paper, we propose a natural scene statistic (NSS)
method, which efficiently uses this information. It is based on the statistical
deviation between the steerable pyramid coefficients of the reference color
image and the degraded one. We propose and analyze the multivariate generalized
Gaussian distribution (MGGD) to model the underlying statistics. In order to
quantify the degradation, we develop and evaluate two measures based
respectively on the Geodesic distance between two MGGDs and on the closed-form
of the Kullback Leibler divergence. We performed an extensive evaluation of
both metrics in various color spaces (RGB, HSV, CIELAB and YCrCb) using the TID
2008 benchmark and the FRTV Phase I validation process. Experimental results
demonstrate the effectiveness of the proposed framework to achieve a good
consistency with human visual perception. Furthermore, the best configuration
is obtained with CIELAB color space associated to KLD deviation measure
Evaluating the Effects of Intergroup Interactions and Color-blind Racism on Perceptions of University Campus Cultural Climate
This study examines college students at a large, public university in the Northeast and their perception of the campus’s cultural climate. The online survey was completed by 362 students whose responses were used to answer the following research questions: “Does the frequency of interactions with people from other cultures affect one’s perception of campus cultural climate?” and “Is there a difference between people who experience color-blind racial attitudes and their perceptions of campus cultural climate compared to those who do not experience color-blind racial attitudes?” Results showed that frequency of interactions was significantly correlated with perceptions of acceptance, and color-blind racial attitudes were significant for all measures of campus cultural climate. Increased representation of minority groups and future research into types of interactions could be beneficial for non-white students’ academic success in secondary education
