Functions | |
| double | hawki_image_float_get_sigma_from_quartile (cpl_image *image) |
| Get a robust estimation of the sigma based on the quartiles. | |
| int | hawki_image_stats_fill_from_frame (cpl_table **image_stats, const cpl_frame *frame, int irow) |
| Fills a table with the statistics of the four detectors of a frame. | |
| int | hawki_image_stats_fill_from_image (cpl_table **image_stats, const cpl_image *image, int llx, int lly, int urx, int ury, int idet, int irow) |
| Fills a table with the statistics of an image. | |
| int | hawki_image_stats_initialize (cpl_table **raw_stats) |
| Initialize the table with all the statistics columns. | |
| int | hawki_image_stats_stats (cpl_table **image_stats, cpl_propertylist **stats_stats) |
| Make the statistics (over image serie) of the each image statistics. | |
| double hawki_image_float_get_sigma_from_quartile | ( | cpl_image * | image | ) |

| int hawki_image_stats_fill_from_frame | ( | cpl_table ** | image_stats, |
| const cpl_frame * | frame, | ||
| int | irow | ||
| ) |
Fills a table with the statistics of the four detectors of a frame.
| image_stats | Table to fill with the statistics |
| frame | The target frame |
| llx | Lower left x position (FITS convention) |
| lly | Lower left y position (FITS convention) |
| urx | Upper right x position (FITS convention) |
| ury | Upper right y position (FITS convention) |
| irow | The row in the table to store the stats (begin in 0) |
This function takes the rectangle of the image given by llx, lly, urx, ury and computes the image statistics. This statistics are stored in the four tables image_stats, one for each detector, using the columns MINIMUM, MAXIMUM, MEDIAN, MEAN, RMS, USED. The USED column is set to 1. The table must have already these columns (call hawki_image_stats_initialize before) The statistics are stored in the row irow.

This function takes the rectangle of the image given by llx, lly, urx, ury and computes the image statistics. This statistics are stored in the table image_stats, using the columns MINIMUM, MAXIMUM, MEDIAN, MEAN, RMS, USED. The USED column is set to 1. The table must have already these columns (call hawki_image_stats_initialize before) The table used to store the data is image_stats[idet], in the row irow.
