To meet the needs of the log curves vectorization, roller scanner can be used to acquire geophysical log images. However, skews are inevitably introduced during the process of long image scanning. Skew correction is an important step to obtain precise digital log curves. Grid lines in log curves can be applied as the basis for skew detection. The(More)
