Typedef Documentation

typedef image* csu::Image
 

typedef struct csu::image_list_node csu::ImageList
 

image_list

This is a data structure that sorts the images by the subject and replicates. s inticates a subject or paticular person and r indicates a replicate of that person. The final data structure should look like this: s1r1-s1r2-s1r3-...-NULL | s2r1-s2r2-s3r3-...-NULL | ... | NULL

This list is to allow for different sized classes for use in the LDA training.

Node fields: filename: name of file image was read from. image_number: index to image in the data matrix next_replicate: pointer to node containing the next replicate next_subject: pointer to node contianing the next subject
