Figure 2From: A semi-automated technique for labeling and counting of apoptosing retinal cellsThe effects of pre-processing illustrated on a DARC image. (A) A raw DARC image. (B) The same image filtered with a Δ2G t filter (C) A pre-processed version of (A) (corrected for local variation in luminance structure). (D) A Laplacian filtered version of (C). Compare (D) to (B) and note presence of additional image structure in (D).Back to article page
