106 unresolved questions extracted from the limitations and future-work sections of 590 Color Science and Applications papers in our library. Each links back to the study that raised it.

What the literature leaves open

  • The paper does not address the limitation of the methods to specific types of surfaces or images. The methods are not compared to other state-of-the-art methods.

    Improved methods of estimating shape from shading using the light source coordinate system · 1985 · DOI

  • Future research can focus on improving the accuracy of the methods. Future research can explore the application of the methods to different types of surfaces and images.

    Improved methods of estimating shape from shading using the light source coordinate system · 1985 · DOI

  • The paper identifies a gap in the study of medieval iconography, particularly in the use of abstract symbols. The study seeks to address this gap by exploring the use of these symbols in medieval art and architecture.

    Windows of Divine Light · 1982 · DOI

  • Developing effective color schemes that can display associations among all variables, statistical and spatial. Criticizing existing schemes and proposing new ones. Balancing the need for color separation with the need for interpretability.

    A Theory for Coloring Bivariate Statistical Maps · 1981 · DOI

  • Empirical testing of different color schemes. Development of new color schemes based on the principles proposed in this paper. Application of the principles to other types of statistical maps.

    A Theory for Coloring Bivariate Statistical Maps · 1981 · DOI

  • Computing optical flow is challenging because only one independent measurement is available from the image sequence at a point. Prior work has not presented a robust algorithm that can handle coarsely quantized image sequences and noise.

    Determining optical flow · 1981 · DOI

  • The lack of specificity concerning the function of color in the media treatment. The difficulty in addressing important questions in research designs due to broad treatment categories.

    AECT/RTD young researcher paper effect of color and monochrome versions of a film on incidental and task-relevant learning · 1980 · DOI

  • There is a lack of understanding of the underlying mechanisms of autokinetic movement and sex differences in its perception. Prior research has not fully explored the effects of stimulus color on afterimage duration and autokinetic movement.

    Sex Differences in the Perception of Autokinetic Movement of an afterimage · 1979 · DOI

  • There is a lack of knowledge concerning the impact of racial differences on task-goal attribute/performance relationships. Prior work has focused on white male and female participants.

    Black—white differences in a goal—setting program · 1977 · DOI

  • The paper notes that the perceptual system must be constructed to function in a very economic way due to the limited size of the computer. The paper acknowledges that the idea is still premature.

    Common and relative components of reflected light as information about the illumination, colour, and three‐dimensional form of objects · 1977 · DOI

  • The paper identifies a gap in the understanding of colour perception and constancy. The paper notes that the theoretical discussion of colour constancy has mainly considered explanations of the constancies as the result of mental processes or sensory processes.

    Common and relative components of reflected light as information about the illumination, colour, and three‐dimensional form of objects · 1977 · DOI

  • Future research could explore the neural mechanisms underlying the neon effect. Future research could also investigate the applications of the neon effect in visual design and perception.

    A new visual illusion: Neonlike color spreading and complementary color induction between subjective contours · 1975 · DOI

  • The paper identifies a gap in our understanding of visual perception and illusion. The paper aims to fill this gap by demonstrating and exploring the neon effect.

    A new visual illusion: Neonlike color spreading and complementary color induction between subjective contours · 1975 · DOI

  • The confounding of race and culture in human populations. The difficulty in determining the genetic determinants of individual differences in behavioral traits. The limited understanding of the basic processes underlying sensitivity to flickering light.

    Racial and cultural differences in sensitivity to flickering light · 1973 · DOI

  • The study of genetic determinants of individual differences in behavioral traits has been limited. There is a lack of research on racial and cultural differences in sensitivity to flickering light.

    Racial and cultural differences in sensitivity to flickering light · 1973 · DOI

  • Further research could investigate the effect of other colors on visual acuity. Further research could investigate the effect of different lighting conditions on visual acuity.

    Bases for the selection of background colors for transparencies · 1973 · DOI

  • There is a need for more research on the relationship between color and visual acuity. There is a need for more research on the effect of different colored backgrounds on visual acuity.

    Bases for the selection of background colors for transparencies · 1973 · DOI

  • Further research can be done to apply the concept of equitable coloring in different contexts. Further research can be done to explore more cases to prove the concept.

    Equitable Coloring · 1973 · DOI

  • The study identifies a gap in our understanding of the relationship between retinal pigmentation and susceptibility to geometric illusions. It notes that previous studies have found mixed results on the topic. The study aims to fill this gap by exploring the relationship using a new spatial-geographical measure.

    RETINAL PIGMENTATION, ILLUSION SUSCEPTIBILITY AND SPACE PERCEPTION · 1971 · DOI

  • Further studies should investigate the effects of other factors on color discrimination. Further studies should analyze the effects of color discrimination on instructional visuals and other applications.

    Visual discrimination of color normals and color deficients · 1971 · DOI

  • Prior work has neglected the perceptual aspect of color in instructional visuals. There is a lack of understanding of the limitations of color deficients in color discrimination tasks.

    Visual discrimination of color normals and color deficients · 1971 · DOI

  • The need for an algebraic development of the theory of perceptual transparency. The lack of a systematic understanding of the necessary conditions for the phenomenon.

    An Algebraic Development of the Theory of Perceptual Transparency · 1970 · DOI
