(If a sample is annealed after deformation, and and then the texture is observed through EBSD)
I'd suggest taking a look at the book Recrystallization and Related Annealing Phenomena by Humphreys and Hatherly.
What we usually call texture is the preferential occurence of particular crystalline.
To answer your question I need to first understand what you call "normal texture"
By Normal texture, I mean that if the EBSD is being carried out on the structure non preferentially, when sample has been deformed and subsequently annealed.
Measure of crystallographic texture is probably what you are seeking. This can be found from the planar and normal anisotropy. Deformed metal has a very high degree of planar anisotropy which results in bad sheet deep-drawing but annealing seeks to enhance the preferred orientation suitable for deep-drawing though grain -growth should be avoided because this can impair the mechanical properties of the sheet. Check up this book; 'Manufacturing Process for Engineering Materials' by Serope Kalpakjian (3rd edition, 1997) by Addison Wesley.
Crystallographic texture can be controlled by variation of the average normal and planar anisotropy. This can be achieved by controlling annealing temperature and previous degree of cold work. Texture with very low degree of planar anisotropy (about zero) and high value of average anisotropy (about unity) is suitable for metal sheet drawing.
Average anisotropy is given as R=1/4( R_0+R_45+R_90) where
R_0 ,R_45,R_90 are plastic strain ratios at 0,45 and 90 degrees to the cold-rolled direction of the sheet
While planar anisotropy can be calculated from the equation;∆R= 1/2( R_0+R_90-2R_45). Plastic Strain Itself = R= (ln w_0⁄w_f )/((l_f w_f)⁄(l_0 w_0 )) where w_0,w_f,l_0 and l_f are widths and lengths of initial and final dimensions of sheet. See also.

Thank you Professor Raabe for your insightful suggestion.
Also, Thank you Dr. Oluwole for your interesting paper.
