hmm…. think twice? think trice? hahah?
may be i should find in torrent for this book ..ngeh2

Stage One – Case Study: JImage


hmm.. since i had go through the experiment stage.. i had to find out the tools needed for the system requirement …by using ” Digital image + Java ” Keyword..alhamdulillah i had flooded is time to choose and read the most related information..insyaallah..

my target for this week is make quick case study about JImage and re-flow my flow chart …

I had found the similar prototype with mine .. nVivo.. the qualitative research tools application ..hmm.. i still try to understand how the implementation of character regonition was done here..hoho…

Insyaallah by in the middle of August I am clear with my system.

The system analysis is the most important part. The precise analysis will help much in the development stage 🙂

Ya Allah, may i faced all circumstances smoothly ameen…

Alhamdulillah, in the experiment stage ^_^|| huhu!

Alhamdulillah, my status now is the experiment stage … hoho I have 3 month to build the prototype from my research algorithm. Caiyoks !
