traind_ocr_net ( Character, Image : : NetId, Class, Iteration, Reduction, Rate : Error )
Training of an OCR network by the input of regions.
The operator traind_ocr_net trains the network
directly via the input of regions in an image.
Any number of regions of an image can be passed.
For each character (region) in Character the
corresponding name (class) Class must be
specified. The grayvalues are passed in Image.
The parameter Error provides information on the
convergence of the network when the procedure has finished.
Parameters
Character (input_object)
|
region(-array) -> object
|
Characters to be trained. |
Image (input_object)
|
region -> object
|
Grayvalues for the characters. |
NetId (input_control)
|
integer -> integer
|
ID of the desired OCR-network. |
Default value: 'integer' |
Class (input_control)
|
string(-array) -> string
|
Class (name) of the characters. |
Default value: ''a'' |
Iteration (input_control)
|
integer -> integer
|
Maximum number of iterations. |
Default value: 10 |
Suggested values: 1, 2, 3, 4, 5, 6, 7, 10, 15, 20 |
Reduction (input_control)
|
real -> real
|
Factor to minimize the error (terminating condition). |
Default value: 0.1 |
Suggested values: 1.5, 2, 3, 4, 5, 6, 7, 10 |
Rate (input_control)
|
real -> real
|
Learning rate for back propagation. |
Default value: 0.01 |
Error (output_control)
|
real -> real
|
Network error. |
Result
If the parameters are correct, the operator
traind_ocr_net returns the value TRUE.
Otherwise an exception will be raised.
