This is a pretty good description of what gray scale dithering is. You can see that the actual black, or white dots don't need to be where the actual representation of the color is. Instead of one gray colored pixel of a certain value, it uses four black or white pixels in a two by two matrix (can be three by three or higher matrices). Remember that two by two matrix is trying to replace one gray matrix so it cannot be placed in the exact position. You will start to generate artifacts, in particular if those patterns start to combine because you notice that they are always skewed in the same way. The 25%, 50% and 75% always use the same pattern. Because of that they can actually create patterns themselves. The shadow may look odd because everything may be set to a gradient which because of the way it represented in the dithering adds all the filled in black parts of the dither together, making it look black even though its actually not that dark. Add to that the I am guessing that it likely started as color. Who the hell uses black and white or gray-scale any more, except artsy folks. So we converted from color to gray-scale and then for whatever reason gray-scale dithered that and then only to about four levels. I can't really tell you what that picture shows. Truthfully they have reduced the amount of graphical information in it so low, that, like you, I can't really tell what it telling us. I suspect that the original photo was color. It was reduced, likely to gray-scale, guessing here, for release in a newspaper? From there it was scanned for Renners publication again, dithering it further? Just my opinion but I will mention that the implementation of image processing algorithms was something that I spent many years doing early in my career. Without seeing the original, I would be far more concerned about that giant splotch in the center of her forehead. Trying to figure out where that came from. 8-) Bill

Damn no Topix edit button.
Remember that two by two matrix is trying to replace one gray PIXEL so it cannot be placed in the exact position.

It looks to me like it was a color photo that they allowed renner to photo-copy, and then renner scanned it into his comp to put on his blog. While I agree we can't def say anything just from this picture but it still looks suspiciously like bruising. Look at the big white blotch, which is definitely an artifact due to dithering. It has a completely random shape, it looks like an artifact caused by the camera. The black spot has a distinctive shape of bruising. I know a little about camera artifacts but am no expert by any stretch of the imagination. So it's just completely coincidental that it looks exactly like a bruise? Look how it ends right where the little fold under her eye is, it follows that line, exactly the way bruises often do. I'm not saying that this is a bruise 100%, I do think it looks like it. I'm sayin that clearly maura's life in Amherst should've been looked into from day one and I would put money down that if this Case is ever solved it will have someone who was close to her, or at least she knew in her prior life being charged for the crime

But I guess that again brings up the question of why didn't they use any up to date pictures of her? One of the pics is clearly her high school senior pic and another is her most likely at the prom. Why? Yea she looks wicked cute in these pics but how r they gonna help find her? Then judging by the size of her cheeks/dimples most of the other pics look pretty old as well. In nov 03 she looked completely different, much much thinner. Did they not have current pics of her? Did they not take any when she was there for the holidays? Is there a reason they didn't want to use current photos? Seems highly unusual for a family to release 2-3 yr old pics of their missing loved one.? This, as with many other aspects of this case, is just not standard operating procedure for a missing persons case. All very logical questions. Keep going with your thoughts I like the logic.

Advocate wrote: <quoted text> According to the copy I have of the Grafton Co Sheriff's Log, at page 19, Faith Westman's call is entered first at 19:27 (7:27 P)... then the call from the SBD residence is entered at 19:43 and presumably that is where dispatch got the description of Maura. The first noted BOL "for a female abt 507 on foot, victim of crash" is entered after the entry of the call from the Atwood residence, so it doesn't look like LE had a description before they talked with SBD. Advocate, I know this now, of course but it still does not explain why the initial chatter we heard was car slid off the road and no one around at about 7pm and shortly later people looking for young female about 5ft 7. This was before call of car in ditch. It always seemed plausible to mme a second accident or that we had missed the initial call somehow. I was sure someone had died when they didnt call rescue out and were just driving around looking for this female.

First you claim you and your husband heard an earleir accident, then you claim that it wasn't you that heard a second accident, then your friend lives on Bradley Hill Rd and then you say she lives on Hill Rd. Now you're again claiming that you did hear a car slide off the road with no one around at about 7PM. Who was looking for her and if she wasn't around how did anyone know she was a female about 5ft 7? Where was this first group of searchers that were just driving around looking for her when the police and EMS were on their way to the "2nd" accident at the Weathered Barn? OK I'm going to get my basket out to collect the peanuts and have my fire extinguisher handy to put out the flames I'm sure to get but I have to say that I think this a a bunch of BS that we've been fed for years. And before mcsmom comes running like her britches are on fire waving old newspaper articles with "evidence" of there being an earlier accident by these two words"about 7" I say don't waste your energy. IMHO when I hear something happened about 7 or about 6 or about 2 it doesn't mean that whatever happened happened exactly at that time or 5 minutes before or after or even 15 minutes before or after. It simply means that something happened about that time.

Some of these posts have been deleted, others unanswered. I've asked if anyone knows who was with her at the parties in Goshen (NYE) and at the dorm party the night her dad was in town. I've asked if anyone ever confirmed the rumor that she had a boyfriend in Amherst, and if so whether he was questioned. I've asked if a gentleman named Mason who used to post on Advocate's board ever was able to obtain the work records for Fred's alibi. I've asked if LE was informed of Maura's past, or if it was just kept out of the public/media. I understand if no one has the answers or is allowed to say. But the response has been to accuse me of having an agenda, working for Renner, tell me I am Beagle or his lawyer etc. Someone also phoned me from a blocked number to "mind my own F-ing business". Related to this? I don't know. But I don't get calls like that on a normal afternoon. Maybe this place is making me paranoid. I just think they are legitimate questions. I am not trying to accuse anyone or pry into anyone's life, or anything like that. I try to be objective and look at the big picture, and part of this picture is missing.

There are some characters on this forum without a doubt. And while I disagree with some of the people here I don't believe hardly any of them are dangerous, though I could be wrong. What I would be more concerned with is I often see that there are 40 people looking at this forum. I have not a clue who probably thirty-five of them are. I suspect that I would be far more concerned with them. The other part is, many, many things we don't know about. Event the things we think we know about is sometimes to have questions. It is the nature of the beast. If there is one fact here that is immutable it is if twenty people look at one fact there is likely to be twenty different opinions on what that fact means. Bill
