$($b$)$ Given an original image as given below in Figure $11.$ Then the convolution process

was done using the Prewitt operator $($based on the provided equations$)$ of Mask $Rx$ and

$Ry($size $33)$ with the original image then the $Qx$ and $Qy$ are produced respectively.

Based on your understanding of Prewitt operator concept in edge detection, analyze

and find the missing value A and $B.$

$[$Diberikan satu gambar asal seperti didalam Rajah $11$ dibawah. Seterusnya proses konvolusi telah

dilaksanakan menggunakan operator topeng Prewitt $Rx$ dan $Ry($size $3x3)$ dengan gambar asal

seterusnya $Qx$ dan $Qy$ terhasil. Bedasarkan pemahaman anda mengenai konsep operator Prewitt

didalam pengesanan hujung, analisa dan cari nilai A dan $B$ yang hilang.$]$
