in accordance with your recent request, we are forwarding two copies of
our Phase 90 Work Statement for Proposal 0 Multiple image
integration, and copies of the related cost estimate.
You will note that the Phase 11 Work Statement refers to two alternatives,
cathode ray tube display, or optical viewing. We have mentioned optical
viewing (or projection) as a second alternative because the possibility
exists that our current EROS development program. with which you are
familiar, will show that an optical approach might be recommended for
implementation. Because of this possibility, we have also provided
-A_ _.2 .LL _.....~.I.,..a nn m tetrials
which might be required in case the optical approach is to be implemented.
The Phase li cost estimate which is attached is based on the electronic
approach as originally proposed in our technical document w or 3 December 1964.

MULTIPLE IMAGE INTEGRATION
Proposal
Phase ii - Work Statement
The results obtained in Phase i, feasibility demonstration, will
Indicate the degree of success expected in the use of electronic correlation
of multiple images. It should be noted that the use of electronic scanning
and correlation does not in Itself determine the method of ?mage transforma-
tion and viewing to be used. There are two alternatives:
1. Cathode ray tube display
2. Optical viewing (or projection)
At the time Phase 11 will be embarked on,
expects to have built
and tested automatic registration viewers of both types, and to have some
knowledge of their relative merits.
The choice of the optimum viewing system for multiple image integration
will therefore be made in consultation with the customer at the start of
Phase 00, and will determine the exact form of the equipment. Most of the
work to be carried ont on Phase I is equally applicable to either viewing
system, as it is concerned with the behavior of the correlator when presented
with material of different geometry, with material containing diurnal or

seasonal variations, or with material of different information content.
Similarly, the work to be carried out in Phase 11 will follow the same
pattern whichever viewing or display system is chosen.
The basic parameters of the equipment to be built remain as described
In the proposal. Provision will be made for three inputs consisting of
film chips or glass plates up to 91 x 91 inches. Any one or any combina-
tion of images may be Independently viewed. Two modes of operation will be
provided:
1. Manual registration
2. Automatic registration using zero-order and first-order
transformations
Circuitry for shadow suppression and automatic weighting of the inputs
according to their information content will be included.
Provision will be made both for viewing and printing out the integrated
Image.
First Period - Four Months
During this period, detailed design of the electronic, optical and
mechanical elements of the prototype Image integration viewer will be
accomplished. Sections of the equipment not previously developed and tested
in Phase J (or in related equipment) will be checked out In the laboratory.
This will include the sequence and flicker control, the commutating unit and
the memory unit. Procurement of materials and components will be initiated.

Phase it Work Statement -3- 24 May 1965
Second Period - Four.Months
Fabrication, assembly, and wiring of the system will be conducted-during
this period. Sub-assemblies will be Individually tested and debugged as far
as possible before incorporation into the main system. Most of the printed
circuit boards and per supplies can be checked in this way. Initial system
debugging and testing will be started.
Third Period - Four Months
Final system adjustments will be made, and system performance as regards
registration with different types of input material will be optimized. The
effectiveness of the shadow suppression circuitry and weighting networks will
be determined.
A final report will be written describing the studies, experimental
results and equipment used. Operating and maintenance instructions for
the multiple Image integration viewer will be compiled.

The purpose of this letter is to clarify and to update the various documents
which submitted in connection with The Combination and

initially, a technical proposal f 3 December 1964, and a covering
letter and cost breakdown of 2 December 1964 were submitted describing a
two-phase program for an estimated price ofi
25X1
Subsequent discussions with the technical personnel indicated an immediate
interest in Phase I only. The estimated price for Phase I was 0 as 25X1
submitted on 2 December 1964. In accordance with this interest and in
response to a specific request for further clarification, a letter was
prepared on February 19, 1965 (Technical Proposal 0 entitled 25X1
"Feasibility Study of Electronic Image Superimposition". This letter of
19 February attempted to clarify the proposed efforts under Phase I as
previously described In the original technical proposal of 3 December 1964.
Furthermore, it was the purpose of this letter to restrict the initial
efforts to integrating multiple coverage photography only and not attempting
to combine and optimize multi-sensor Imagery as well. This restriction was
Imposed at the request of the technical personnel with whom the proposed
efforts had been discussed.
Since the submittal of the last document concerning the proposed program
on 19 February 1965, various tests which have a bearing on the proposed
efforts were conducted. A test report describing the various experiments
conducted on the ARES Viewer was passed on as an information copy to the
technical personnel concerned with the proposed image Integration efforts.
As a result of our studies and tests concerning the general applicability
of ARES technology to the problem of Image Integration which were carried
out since February 19, 1965, we have somewhat modified the scope of work
previously suggested In the document i---- ]of 19 February 1965. This 7F X1
mocitricatlon does not change the basic objectives but reflects the experience
gained during the last few months. The objective of the efforts during these
four months will be to demonstrate the feasibility of integrating multiple
coverage photography by electronic techniques using a modified ARES Viewer.
An appropriate, brief and descriptive title for these efforts appears to be
"Feasibility Demonstration - ARES Image integration".

FEASIBILITY DEMONSTRATION -
5X1
The objective of the proposed four months' program will be to
demonstrate the feasibility of combining and optimizing multiple coverage
photography for the purpose of image integration by electronic techniques
using a modified ARES Viewer.
The modifications of an RES Viewer will include:
1. The addition of manually controlled second and third order
transformations to correct for residual distortion of oblique
and panoramic material.
2. The design and implementation of a variable gamma video amplifier
to correct for differences in the gamma of the input material.
3. The design and implementation of circuitry for shadow suppression
to improve correlation of photographic imagery taken at different
times of day for different seasons of the year.
In addition to the above modifications of the ARES viewer, theoretical
and experimental work will be performed concerning 1) methods of correcting
relief displacements by the use of high order transformations; 2) methods
of weighting the input material in accordance with its information content
in order to avoid degradation of the integrated image.

-2- 10 May 1965
The feasibility of integrating multiple coverage photograplpy will be
demonstrated with representative photographic material of different
Inherent geometry and exterior orientation. The Integrated images will be
added or subtracted electronically and displayed on a single cathode ray
tube. Photographic records of the output irhagery will be obtained indicating
the degree of correlation achieved with various types of Input material.
During the last stages mf the proposed feasibility demonstration it may be
desirable to ship the modified ARES Viewer to
Data Analysis Center
Advisability of such transfer of equipment and
further experimental work will be decided upon after consultation with the
cognizant technical monitor.
Monthly letter progress reports will be submitted during the proposed
study. The end product of the proposed efforts will be a final report
comprising 1) a summary of all theoretical and experimental work conducted
during the study, and 2), the definition of all pertinent design parameters
for a multiple image integration viewer based on the results of the
experimental verification to be conducted under the proposed program.
