objective c - Image processing on the iPhone -

-

I would like to apply image processing to photos taken on the iPhone. This processing will include 2D matrix conversions.

I'm afraid that performance with nested NSArrays is very bad What is the correct way to manipulate pixel-based images? Should I just use the array allocated with malloc

? Engine available in the iPhone SDK? Or maybe core graphics? Apple has described the different imaging techniques available on the iPhone. Unfortunately, there is nothing good in the image kit so far on the iPhone.

oracle - The fastest way to check if some records in a database table? -

-
I have a big table to work with. I have to see that there are some records whose parent_id is equal to my passing value. Currently I do this by implementing "my_table using select count (*) where parent_id =: id"; If the result> 0, it means that they exist. Because this is a very large table, and I do not care what the actual number of records present, I just want to know if it exists, so I think count (*) Bit is disabled. How do I apply this requirement most quickly? I'm using Oracle 10. # Tips for Hibernation & amp; Tricks It suggests writing in such a way: Integer number = (integer) session .createQuery ("Select Count (*) to ....").

If you are not interested in the number of records, then there is an EXISTS query one: Select 'y'
