Accurately View All The Details


Vision provides far more information than can be expressed in virtually any other form. As a consequence, many engineering technologies rely on visual representations to convey information.

The human eye distinguishes approximately 32 levels of contrast. Digital images contain hundreds to billions of levels of contrast. Lucis shifts the relative emphasis of contrast variances so you can view the information you wish to see.

Lucis employs Differential Hysteresis Processing (DHP), a sophisticated image-processing algorithm, to extract and highlight patterns within a digital image characterized by variations in image intensity. This capability enhances and reveals image detail that would otherwise be undetectable to the human eye. Lucis accomplishes this by mathematically processing the image as a two-dimensional array of numeric data, selectively detecting and emphasizing certain aspects of the visual information, and converting the result back into an image. Lucis enhances and modifies images unlike other image processing methods.

Lucis' ability to enhance image information is remarkable. In addition, Lucis uses only two variables (two sliders), making Lucis incredibly easy to use. For most scientific and medical applications only one slider is needed, the Enhance Detail slider. More detail on how Lucis works.

Below is the original image of a bee stinger taken using a transmission optical microscope using phase contrast. The top image is the Lucis - processed image.

Lucis Pro Image

To enhance detail throughout the image, open an image in Lucis and move the Enhance Detail slider to the left.

Contrast variances less than the slider value are magnified and contrast variances equal to or greater than the slider value are diminished.

Because Lucis works with relative contrasts, Lucis enhances detail in the bright, dark and mid-range areas simultaneously.

Lucis accurately enhances contrast differences as small as 3 intensity levels.

The Smooth Detail slider diminishes the smallest image detail so noise is reduced, but this operation is rarely used in scientific and medical applications.

For multichannel images such as fluorescence microscopy, Lucis can enhance each RGB channel separately.
