Lessons learned
Fig. 6.1
Some of the important technical knowledge we have gained (which is discussed in detail in the three "Image processing" sections) includes:
image-enhancement techniques
imadjust() function
morphological filters
imopen() and imclose() functions
imerose() and imdilate() functions (which are the "erosion" and "dilation" operations that define imopen() and imclose())
imfill()
area-based filters
bwpropfilt(_, 'area', 1) (for filtering for the largest area)
region-property-measurement techniques
regionprops()
distance transforms
bwdist()
shape-inserting and text-inserting techniques
insertShape()
insertText
We have also learned some lessons on general problem solving, including:
it is much more efficient to work with a graphical user interface (GUI) than with hand-written source code
for example, the Image Segmenter App should be the starting point for any image segmentation task
it is never too late to pause what we have been working on and explore an alternative approach
this attitude led us to discover the imfindcircles() function in our circular-shape-detection task
