' r o y4r7
The proposed project, designated "Research on Photo Interpreter Performance,"
would follow up a pilot study on "Photographic Ima e Recognition as a Function of
Ground Resolution" which was conducted byl Human Factors Research, 25X1
and. NPIC, to prove that information from this kind of experimental research is
meaningful and useful to the photographic intelligence process. The proposed
effort, endorsed by DD/S&T on merit of the successful pilot study, would be
funded by NPIC F__ I would make use of NPIC facilities and experimental 25X1
subjects, and would be of joint interest to DD/S&T and NPIC.
This project is provided for in the NPIC's FY64 financial plan at the
level under two categories of Object Class 700: "Viewers and Other
Photo Interpretation Equipment"i J, and "Special Techniques and Develop-
ment Studies" F_ J The remaining funds are available as a result of
deferment of other projects for further investigation.
II. Objectives
In extending the findings of the pilot study, the proposed program would
investigate three principal and basic areas of concern. Objectives would. con-
sequently be:
A. To determine the relation between P.I. performance and ground resolution
of photography.
B. To assess the effects of stereo image viewing (as opposed to monocular
viewing) as well as the effect of mixed-resolution stereo pairs on P.I.
performance.
C. To investigate the effects of color photography on P.I. performance.
. Findings will supply objective measurements which will serve to aid in the
development and use of collection systems and exploitation equipment.

III. Background
In NPIC?s particular intelligence effort, "man" -- the photo interpreter --
is the key element and yet he remains the most unknown factor in the total picture.

There are proven techniques for attaching numbers to systems capability
(currently in terms of "modulation transfer function"); but there is no
means, to date, of quantitatively accounting for or predicting or enhancing
human performance as it relates to the quality and kinds of materials
available in the interpretation task. This vagueness inhibits our develop-
ment programs.
In general terms, we want first to ask ourselves what threshold of
quality is incontravertibly set by accountable human factors? What degree
of image quality is really needed. for specific targets (for this will vary
and exactly what details do we want to be able to see in various targets?
When do stereo and. color, for instance, provide more information to the
human visual system?
At long last, a value could. be put on the direct benefits of resolution,
stereo and color:
A. Results from the resolution study will aid, in assessing the relative
intelligence worth of various collection systems which yield different
ground. resolutions. This objective, in a skeletal version, formed
the basis of the pilot study, but would now be specifically correlated
with types and priorities of targets suggested by the operational
components cooperating in the study. The resolution study will
establish a benchmark from which effects of other physical factors
can be measured.
B. From an investigation of stereo, NPIC would finally have in its
hands some relative numbers for evaluating (or justifying) stereo
as it directly contributes to identifying specific kinds of targets.
C. The study on color will, include investigations of P.I. performance
with monocular color images, of stereo images in which (1) both images
are in color and (2) one image is in color and the other is in black &
white. Variations in ground resolution will be introduced for both
the monocular and. stereo images. Results will be useful in deciding
and detailing the roles that color might, with some degree of
assurance, take in collection and. exploitation.
In what is a relatively unexplored area, the first facts and findings
will be necessarily basic and therefore important, with many side benefits.
Additional studies may be carried on simultaneously -- as they have an
effect upon the overall investigation. For example: experiments at Harvard
University's Center for Cognitive Studies suggest that image identification
of degraded. images can be strongly influenced by pre-conceptions, such as
the sort of pre.-conception. a P.I. might unconsciously have gained in his own
specialization (of target-type). Called "response perseveration," it can
decidedly interfere with recognition. It also encourages a person's first
notion about lower-grade information to stick in his mind., obstructing other
alternatives. Findings from such research will be applied to the proposed

project and, in this case, might be incorporated as multiple-choice testing
techniques. Further exploration. and application might prescribe a scheme,
for instance, of presenting collateral information to the P.I. and of
assigning (or rotating) tasks for the most objective interpretation possible.
Another obvious offshoot is an investigation of basic aptitudes, back-
ground and. personality traits which are essential to the successfully per-
forming P.I.
Other factors of contiguous or future concern are:
1. contrast and brightness range 7. scene change detection
2. granularity 8. season/terrain
3. sun altitude and azimuth 9. searching and viewing time
4. obliquity 10. viewing equipment/scale
5. infrared photography 11. collateral information
6. real color v.s. false color 12. individual. P.I. differences
IV. Technical Specifications
All findings and figures will be submitted in report form and will also
be represented in graphs. Graphs, covering all important target-types, will
plot ground resolution (from a range of 1-10 feet) against target identifi-
cation. Curves for the same target-type will contrast stereo with monoscopic
viewing and color with black & white.
With the help of operational. components a survey of targets of interest
(which are available within the U.S.) was designated. Photography should
include:
1. Missiles (ICBM)
2. Electronics (antennae)
3. Military (air fields and submarine sites, with nuclear facilities)
4. Storage (military, ammo, BW/CW)
5. Industry
6. Transportation (land., sea, ports and harbors)
7. Power
For the following reasons, actual mission photography is unsuitable for
the project and special. flights must be flown: (1) techniques for simulating
scale and resolution of photography require known and exact processing para-
meters so that accurate transfer function can be determined. (2) Images must
be selected by specific recognition characteristics for purposes of testing.
(3) For purposes of correlation, color photography must be identical to black &
white photography and consequently must be shot at the exact same time.

However, as a doublecheck and also in the process of specifying sites to be
photographed, the researchers will review Air Force reconnaissance (data) test
flights. If material is suitable, it will be used, It is probably from this
source that materials will be obtained. for pretests, the purpose of which is to
determine meaningful alternatives for mutiple-choice answers,
The OSA/Air Force will be responsible for providing the aircraft, cameras,
and original film-processing necessary for collecting the photography. In the
event that ground. targets are required, the sponsor will. make the necessary
arrangements.
Since simulation techniques will. be used, for degrading resolution, the
initial, photography must be of high quality (a ground resolution of 6").
Photography must also cover a long strip of terrain at least z mile wide It
must provide at least 60% overlap between frames. Targets must be covered in
both color and black & white. Further specifications have been discussed with
-the proposed contractors, and there is leeway for selecting the remaining
parameters in terms of our logistical convenience.

DDS&.T. The Office of Logistics has taken the preliminary steps necessary
for contract negotiation.
A thorough survey of research and literature on the psycho-physiological
aspects of the P.I. function was part of an earlier study performed for. NPIC
by in 1960. Recently, has reviewed current research 25MI
in this field with NPIC technical personnel, and it was consequently concluded

that other efforts are not applicable to NPIC's standard of materials --
that is, based upon the quality of material now being acquired. It is also
felt that (1). techniques used to date in service-sponsored. studies of photo
interpretation were inadequate in experimental design and did not yield
objective criteria; and (2). that these and other studies did. not ask
questions analogous to NPIC interpretation tasks.
As a result, the contractors will from necessity collaborate closely
with NPIC P.I.s and will correlate questions with the kinds of intelligence
requirements presently levied on the Center. Looking to the future,
projected requirements for image recognition will. also be incorporated
into the testing, since current intelligence requirements are most often
defined to fit NPIC's present capability and. not necessarily to exceed it.
As a general reference on the project, will submit a
short summary/evaluation of current and recent research which he judges
partially relevant to this proposed undertaking -- either in. terms of
techniques or findings.
VII. Security
The contract will. be SC-1 and. association with the Agency will be
