I did not pay attention to this problem at first, just through the trap door feel very mealy, why not directly call Write_char in Level 3 user code, today's own writing program want to call the code snippet, only to find the big problem. I wrote a process similar to Write_char, with the following code:Dividing_line:push%GSPUSHL%EBXPUSHL%ecxmovl $1,%ecx/* Output 1 spaces ' */movl $SCRN _SEL,%EBXMOVW%bx,%gs1:movl scr_loc,% EBXSHL $1,%ebxmovb $32,%gs: (%

[Path to Java Development] (19) Long cache
Long has a small trap, that is, within the range of-128 to 127, Long. the long instances returned by valueOf (Long l) are the same, and the returned instances are different each time valueOf (long l) is used outside this range.
Example:
System.out.println(Long.valueOf(-129) == Long.valueOf(-129)); // false
System.out.println(Long.valueOf(-128) == Long.valueOf(-

course, there are many improvements to this disadvantage ). The core idea of bovw is as follows.
Some people have asked, there are many methods to extract image features, such as sift Feature Extraction and star feature extraction. Why do we need to use bovw models to characterize the image? Because of Sift, the feature vectors obtained by star feature extraction machines are multidimensional. For example, the sift vectors are 128 dimensions, and an
