Color image processing

Jean Serra

The seminar attempts to treat four aspects of digital colour imagery
  1. It begins with a critical analysis of the current colour spaces. Many of these spaces were originally developed for computer graphic applications, and are not suitable for quantitative image processing (lack of independence between chromatic and not chromatic data, measurements which do not satisfy the triangular inequality...). Some changes are proposed for improving the current spaces, and new spaces are introduced.
  2. The second point, more specific, deals with the hue, i.e., with data that are defined on the unit circle. The round table structure of the unit circle may seem contradictory with the need of suprema and infima required by lattices. However, one can overcome the contradiction either by accepting increment-based operators only, or by introducing criteria of clusters, or finally by using the hue as a way to label the space.
  3. The algorithms which are based on the product lattice of the three colours RGB introduce parasite supplementary colours. Such an effect disappears when the lattice under study is totally ordered (e.g., lexicographic order). To which extend do we need a total order, and if so, which one? These questions are approached within the scope of filtering.
  4. The segmentation techniques generally involve gradients. Consequently, the first part of the lecture is devoted to introduce various colour gradients and increments, and to and compare their performances. The second part applies to colour images the segmentation techniques based on watersheds and on connections. The last part of the lecture concerns multispectral data such as those obtained in polarized microscopy.
