T.QUANTITATIVE EVALUATION OF SYSTEM ENHANCEMENT 
EFFECT FOR GEOLOGICAL LINEAMENT. 
According to the Feedback Dynamic Recognition 
Pattern, this paper has calculated respective IL 
valus of various functions in common use for 
enhancing lineament. On the basis of total 
statistics, these values were obtained from 1500 
sheet of images concerned with various physical 
features. Due to lacking statistics to some 
specific areas, thus in statistics this experiment 
did not carry out area classification with variety 
of physical feature. The grade I of signal Y, or 
selected maximal grade in a number of X signal 
grades responding to same target,was obtained from 
respective X signals of 10 functions ( or series 
connection programs). Statistic number of each 
function was more than ten times number of I(C)J 
distribution state, about above 140 strips of 
lineaments.It can be known from examples stated by 
section 5, that required statistic number need not 
reach such large value in practice. The percentile 
IL values of various functions obtained by this 
experiment can be written in big or small sequence, 
as follows (percent symbol does not be listed): 
HIST NORMALIZE ( 43) ; CONVOLVE( 38) ; LOCAL! ENHANCE 35) ; 
HIST!EQ(33) ;PLIM(32); SCALE(32) ; SELF-MULTIPLY ( 31) ; 
KL-PRINCIPAL COMPONENT(30); HADMARD(29);FFT1D(28); 
LOGARITHM( 27 ) ; KL’ TRANSFORM( 23) ;RATIO( 19) ; CLUSTER( 1 
71) ; MSS! BAND-7 (26) ;MSS! BAND-5 (22) ;MSS' BAND-4(18). 
These IL values concerned with original single 
band images reflect visual recognizable and 
responsive ability to image signals, namely, the 
visual interpretation is considered as function 
transform, these differences among IL values are 
consistent with physical mechanism analysis 
concerned with band property and geological 
environment. The IL values of  function-CONVOLVE 
and LOCAL'ENHANCE belong to high level in system, 
that is concerned with respective property of 
themselves,and is consistent with most qualitative 
evaluation conclusions. These quantitative IL va- 
lues have also revealed difference between theory 
and practice of some functions, such as function 
-FFT1D or KL'TRANSFORM. 
Putting various functions to participate in 
parallel connection operation in big or small 
order of their respective IL value, can obtain 
parallel connection system (IL)p values from 
formula (5), as shown in List 7-1.

The formula (5) has larger practicality. In 
practice, people can usually obtain satisfactory 
results for lineament only with 4-5 functions, from 
List 7-1 , it can be known that corresponds to 
having tapped 90% system gain potential; for some 
images which are processed difficultly, that often 
want over five functions to participate in 
operation, but incremental gain signals are less, 
that is consistent with retarded appearance of 
(IL)p increasing velocity in this range shown as 
List 7-1. 
For those series connection programs through 
practical check, according to name of function 
66 
participating in main-processing, whose IL values 
can be arranged in order of big or small, as 
follows: : 
COMPOSITION OF KL'COMPONENT WITH ORIGINAL IMAGES 
(45); CONVOLVE(44); NEGATIVE(42); KL PRINCIPAL 
COMPONENT ( 41 ) ; LOCAL! ENHANCE ( 37 ) ;KL' TRANSFORM( 34) ; 
SELF-MULTIPLY (34); RATIO(31). 
These respective IL values of above-mentioned main- 
processing functions, due to their having 
participated in series connection operation, all 
have respective improvement over IL value obtained 
singly by oneself. If these programs sequentially 
participate in parallel connection operation in 
big or small order of their respective IL value , 
those obtained (IL)p values can be listed in List 
7-2: 
List 7-2 parallel connection system CIL)p values

That can be known from above, if we put only 4 
programs to participate in parallel connection 
operation, we can tap 9094 system gain potential. 
Series connection programs and functions can also 
participate in parallel connection operation 
together. 
8. CONCLUSION 
For evaluating IPOS enhancement effect, the 
qualitative evaluation was putted first 
previously. Except that subjectivity and 
localization in its weakness , this evaluation 
hardly considered the actualities information of 
original image, and only regarded "GOOD" and "BAD" 
or "HAVING" and "NOTHING" of enhanced results as 
standard, that is perplexed by surface phenomenon 
easily. From these composite signals I(C)J, we can 
carry out quantitative and qualitative evaluation 
accurately. On the statistic basis of 14 kinds of 
composite probability distribution results, we can 
evaluate enhanced effect by single quantitative 
parameter IL, and can consider all possible cases 
overall and really. 
The IL value represents function or system self 
enhancement feature, thus can be used as a means 
checking new functions or programs. Some functions 
could be a series connection program composed of 
various procedures, if strict measure leads to 
increment of procedure number, as formula (6) its 
enhancement effect could be just the opposite to 
what one wished. 
To use the series-parallel connection programs,can 
give full play to system enhancement potential.For 
image enhancement of designated target,we need not 
employ all system functions, with reference to 
those respective IL values of various functions or 
programs which is concerned with designated target, 
we. can compose a subsystem with definite functions, 
whose effect can represent enhancement potential 
of the whole system. 
To counter the geological lineament,this paper has 
recounted some quantitative parameters concerned 
with system and functions, which have definite 
directive action in the image processing dynamic 
policy-making course,from which we can obtain many 
lineaments enhanced results quickly and 
effectively.
